What Is the Most Metallic Element

The most metallic element is francium. However, francium is a man-made element, except for one isotope, and all isotopes are so radioactive they almost instantly decay into another element. The natural element with the highest metallic character is cesium, which is found directly above francium on the periodic table. How Metallic Character Works There are several properties associated with metals. The degree that an element displays these properties is its metallic character or metallicity. Metallic character is a sum of certain  chemical properties, all associated with how readily an atom of an element can lose its outermost or valence electrons. These properties include: Easily reducedCan displace hydrogen from dilute acidsForms basic oxides and chlorides Metals also tend to be shiny, good conductors of heat and electricity, ductile, malleable, and hard, but these physical properties are not the basis of metallic character. Periodic Table Trends for Metallic Character You can predict the metallic character of an element using the periodic table. Metallic character increases as you move down a group (column) of the periodic table. This is because atoms gain electron shell levels as you move down the table. Although there are more protons (more positive charge) as you move down a group, the outer shell of electrons is further away from the nucleus, so the valence electrons are easier to strip away from atoms.Metallic character decreases as you move from left to right across a period (row) of the periodic table. This is because atoms more readily accept electrons to fill an electron shell as you move across a period. Elements on the left side of the periodic table are more likely to donate an electron than elements on the right side of the table. Thus, the most metallic character is found in ​an  element on the lower lefthand side of the periodic table.

Managing Users in Heterogeneous IT Landscapes - 666 Words

One of the main challenge organizations is facing is managing users in heterogeneous IT landscapes. Organizations are preferring the access control via role management (Franqueira, V. N. L et al., 2012). With the evolving responsibilities, the system landscape is becoming more and more complex and difficult to manage and track (SAP1, 2012). With SAP NetWeaver Identity Management (IdM), we can manage identities and their authorizations centrally in both SAP and non-SAP system landscapes. This comes with employee self-services and SAP BusinessObjects Access Control formerly GRC (Governance, risk management, and compliance) (SAP2, 2012) integration which helps in risk detection and mitigation and makes identity management more compliant. Using NetWeaver IdM, a highly customizable framework we can provide joint authentication for all business processes and a single sign-on as a secure identity management solution. Driving factors for implementation of Identity management include a decre ase in operational cost, frequently evolving business processes with increasing complexity and inability to de-provision a user completely. Many challenges come from the desire to grant single-sign-on access to collections of resources that might have contradictory access-protection rules (Buell, D.A. et al., 2003). The functions of NetWeaver IdM include role management, Identity Virtualization, data synchronization, customized work-flows and approval process, password management, identityShow MoreRelatedFog Computing That Its Adoption And Implementation Can Be Improved Essay1211 Words   |  5 Pagesnumerous issues that are inherent in these systems including unreliable level of latency and issues related to mobility.

Contextual Knowledge in Program Planning A Personal Reflection Free Essays

Program planning is a challenging and complex task. Its complexity lies not only in the program details or the audience to which the program is targeted to, but in the different personalities or experiences of the planners. Many times as planners, we communicate what we are. We will write a custom essay sample on Contextual Knowledge in Program Planning: A Personal Reflection or any similar topic only for you Order Now We want to inculcate our belief and personal perception to audience including our biases. Planning itself requires much effort. With interpersonal issues among planners, the issue becomes more difficult to deal with as experts rub against each other. Answer to Question 1 Planning involves the participation of different stakeholders or team members. Different ideas flow and clash against each other. Power issues surface and the battle over whose idea or whose proposal is better rages. When faced with this circumstance, I tend to speak out my mind. I listen to others’ thought as well. I go over the positive and negative aspects of each idea. I weigh the options and vote for the best one. I respect each person or team member. I realized that when it comes to power relations, there are different motivations lying beneath. At first, I believed planners are sincere and focused in doing service. Yet, when I had my first brush with power struggles within my circle, it dawned on me that some planners have their personal agenda. It could be something beneficial to them. So far, there is nothing I would like to change about my current beliefs. But I want to reinforce the notion that planners must be objective and must be wiling to let go of personal biases or motivation for the good of many. Answer to Question 2 Listening and open communication are the skills that I utilize in every planning session. Listening requires much effort as it involves more than hearing different ideas. Listening is digesting each idea and respecting it. Listening is acknowledging one planner’s thoughts and knowledge. Communication, on the other hand, is being open with the possibilities of accepting and trying out the ideas. It may also mean acceptance for every suggestion turned down. Open communication is healthy and acts as a bridge. If there is something that I would really want to practice in my belief system is the win-win solution. Negotiation is coming up with the best solution with minor compromises that serve both rallying parties. Answer to Question 3 Planning a program for adults is an enjoyable task. Ethically speaking, adults are willing learners who are experts in their own right. They can make decisions with or without outside intervention. Each adult is a well of knowledge; having gone through different life experiences. These learning are brought out through a participatory learning process. Usually, my beliefs are challenged when a co-planner becomes so very intellectual in approach and dismisses my suggestion that adult learners are learned, by virtue of experience. I usually respond by reasoning that through the adult learner’s participation, the program can be much more engaging with the learner themselves speaking out and contributing to the discussion. The conventional funnel method or top-down approach in teaching is not the best way. I get frustrated when participatory learning is bypassed. I feel like the learners have so much to offer. As a program planner, I would like to stress on the value of a person or a learner in the learning process as very ethical and critical. This is one reality that I would like to emphasize in my practice. A learner-centered program is needed to effect change in a training program. There are messages than can be more effectively conveyed to the learners or audience through participatory method. People learn by themselves. Learning is not imposed or enforced. In his 1982 book, Living, Loving and Learning, Buscaglia cited Carl Rogers who wrote: You know that I don’t believe that anyone has ever thought anything to anyone. I question the efficacy of teaching. The only thing that I know is that anyone who wants to learn will learn. And maybe a teacher is a facilitator, a person who puts things down and shows people how exciting and wonderful it is and asks them to eat. (p. 7) We are all learners. We learn from each other. Even experts learn many things from their participants. No man has the monopoly of knowledge and experiences. One man’s learning differs from others. We all have our own way of learning. Answer to Question 4b I have not left a planning situation even if I am not totally sold to the agreed ideas or methods; even if my own suggestions are downplayed. I stayed to learn from them. I still joined to see if their methods based on their belief system will work. It is all about respect and giving opportunities to other parties to have their own way. I hanged on to see the results of the evaluation. Probably, what would make me leave is the honest and face-to-face rejection of my ideas after a poor training program. I would leave if they lost trust and direct all the blame to me. I would humbly resign. I will not burn the bridge between us but hope to re-connect with them again in the future, should they need my services again. After all, the world is small and who knows, we may end up needing one another at the end of the road someday. References Buscaglia, L. (1982). Living, loving and learning. New York: Random House.

Rock And Roll Essay Example For Students

Rock And Roll Essay In this essay, Im going to introduce to the reader a topic not touched a lot because of its complexity and its avoidance by conservative adults. This topic is, of course, Rock Music. During one week, I looked for information in the library and at my house, and from the information I gathered and my one knowledge about the topic, Im going to lead the reader to a better understanding of Rock n Roll. I chose to do Rock music because I can identify myself with it. Rock music is very complex. In fact Its stylistic scope is to broad to be encompassed by any single definition (Rock Music, Groliers, p.1). The nearest definition suggests a kind of music that represents and speaks for the teenage society. This music is characterized by using a heavy beat. In this essay, Im going to divide Rock music into four sections: Rock of the 50s, of the 60s, of the 70s and of the 80s. Within these sections Im also going to discuss several sub-topics such as famous composers and groups, and characteristic s of the music. The first section of this essay is Rock n Roll of the 1950s, when Rock n Roll was born. It emerged from rhythm and blues, a music similar to jazz played by blacks. This kind of music started to attract white teenagers. Disc jockey Alan Freed was the one who introduced this music and later gave it the name of Rock n Roll. Record companies distributed records played by whites but composed by blacks. Whites were frustrated because there werent any white artists and they didnt want the blacks to be the stars until Bill Haley appeared with his Rock Around the Clock. In this decade, Elvis Presley introduced a music that was sexual suggestive and outraged dull adults. In time he changed the style of the music by adopting a country and western style and became a national hero. By the end of this decade and the start of the next, Rock n Roll started to decline because it was formula ridden and it was too sentimental. Teenage audiences transferred their allegiance to Folk musi c. In 1963 the renewal of Rock n Roll came when The Beatles started to play. The Beatles, for some the best rock group ever, were from Liverpool, England. Through the 60s, The Beatles dominated the record industries and with their dominant instrumentation, which included: electric leads, rhythm, and bass guitar, drums and sometimes an electric organ, changed the name of Rock n Roll to just Rock. During the 1960s many other styles of music arose from Rock like, Motown, Soul music, Jazz-rock , Folk-rock and others. Folk-Rock the most appreciated of this derivations and was first suggested by Bob Dylan. This kind of music brought to folk music a hard beat and amplification; and to Rock, a new poetic style. California was one of the major centers of rock activity and experimentation during the decade. First it was characterize for its surfing music, a very joyful music that reflected the fun people had while surfing. The Beach Boys were the ones who introduced this kind of music. At the end of the century this happy kind of music changed to a more rebellious style that was designated the name of hippie music. Groups that played this music were Country Joe and The Mamas and The Papas. Along with this hippie ideas popularity of hallucinogenic drugs produced a psychedelic style of music called Acid Rock. By the end of the 60s the distinctions between Rock n Roll and Rock were evident. The early instruments- saxophone, piano, amplified guitar, and drums- had been changed to electric guitar and bass, amplified drums and other electronic devices. Not only did the instruments change but so did the ideas behind the music. For example, to the lyrics of teenage love and adolescent concerns were added social commentary, glorification of drugs and free-association poetry(Rock Music, Groliers, p.1). Groups like The Beach Boys, Crew Cuts and The Everly Brothers were replaced by more imaginative, non-descriptive names groups like The Who, Jefferson Airplane, Big Brother and Hold ing Company. The Who, the most famous of these groups, were originally from England and were reknowned because of their bizarre stage performances, they would destroy their instruments after their performance finished. The Who was one of the first rock groups. In the 70s, the common barriers of rock broke into more divisions, like hard rock and mellow rock. Hard Rock was extremely loud and electronically amplified and Mellow Rock was softer and with acoustic instruments. In 1972, in Jamaica, a new style of music was created called Reggae. Reggae is a mixture of rock, soul, calypso and Latin music. The king of Reggae was Bob Marley. Other styles more in rocks borders, since Reggae was more latin than rock, were created in the middle of this century, like: bubble gum rock, a funny playful music directed to the youngest fans, Punk Rock, a loud, hard rock style derived from acid rock and marked by its extremes of costume and staging (Rock Music, Encarta, p.1), and Heavy Metal, which con tinued the approach to Acid Rock but with a simpler musical dimension but relying upon the power of repetitiveness, loud volume, and electronic distortion. .uc0ceefca9c423e5a43e1385dcfa74239 , .uc0ceefca9c423e5a43e1385dcfa74239 .postImageUrl , .uc0ceefca9c423e5a43e1385dcfa74239 .centered-text-area { min-height: 80px; position: relative; } .uc0ceefca9c423e5a43e1385dcfa74239 , .uc0ceefca9c423e5a43e1385dcfa74239:hover , .uc0ceefca9c423e5a43e1385dcfa74239:visited , .uc0ceefca9c423e5a43e1385dcfa74239:active { border:0!important; } .uc0ceefca9c423e5a43e1385dcfa74239 .clearfix:after { content: ""; display: table; clear: both; } .uc0ceefca9c423e5a43e1385dcfa74239 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uc0ceefca9c423e5a43e1385dcfa74239:active , .uc0ceefca9c423e5a43e1385dcfa74239:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uc0ceefca9c423e5a43e1385dcfa74239 .centered-text-area { width: 100%; position: relative ; } .uc0ceefca9c423e5a43e1385dcfa74239 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uc0ceefca9c423e5a43e1385dcfa74239 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uc0ceefca9c423e5a43e1385dcfa74239 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uc0ceefca9c423e5a43e1385dcfa74239:hover .ctaButton { background-color: #34495E!important; } .uc0ceefca9c423e5a43e1385dcfa74239 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uc0ceefca9c423e5a43e1385dcfa74239 .uc0ceefca9c423e5a43e1385dcfa74239-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uc0ceefca9c423e5a43e1385dcfa74239:after { content: ""; display: block; clear: both; } READ: General Prologue: Human Dishonesty, Stupidity and Essay One famous group of Heavy Metal was Led Zeppelin, a British group that was formed in 1968 by Jimmy Page (lead guitar), Robert Plant (lead singer), John Paul Jones (pianist and bassist) and John Bonham (drummer). Most music of this decade was intended to be listened to, but not to be danced. But this intention wasnt kept by Disco music that arose in 1977 and was especially for dancing. One great group of Disco music were the Bee Gees. Disco music was described by rock fans as mechanical, commercial and unlyrical (which is true). At the end of this decade, rock, again became a dominant cultural force. The last but not least section of this essay is rock of the 80s. At the start of this last decade, rock groups became more production oriented, mainly because of the sudden explosion of videos. This new sensation was a good way to sell music to the people. Heavy metal bands were greatly pushed by videos, but most helped were the popular performers like Michael Jackson, Prince and Boy George. The influence of British bands of punk, disco, reggae and pop-rock was still big in the U.S. Rock scene. At the same time, there of nostalgia to return to the older pre rock music, like rhythm and blues, which was suggested by played by Elvis Costello. By the middle of the 80s, almost every country had begun to support indigenous music, and at the end of this a vigorous talk-song style called rap became extremely popular among urban black teenagers (Rock Music, Encarta, p.1.). Rock music taught me to appreciate things in a different way. Ive learned this since rock is not an exact science, it can change. In fact Rock music helps me relax ( I would have been able to finish writing this essay with rock music). After writing this essay I have learned the origins of rock and the branches of it, but that wasnt my intention. I wrote this essay to express myself with it because I feel I can show myself with rock music. I think rock has become social phenomenal.
