History Of Affirimitive Action essays

History Of Affirimitive Action essays Affirmative Action in the United States consists of the active efforts that take into account race, sex and national origin for the purpose of remedying and preventing discrimination. Under the Civil Rights Act of 1964, the federal government requires certain businesses and educational institutions that receive federal funds to develop affirmative action programs. Such policies are enforced and monitored by both The Office of Federal Contract Compliance and The Equal Employment Opportunity Commission (EEOC) (Lazear 37). The most noteworthy criticism of affirmative action is that of the white male population who insists that such programs are forms of "reverse discrimination". In contrast to their view, the United States Commission on Civil Rights argued until 1983 that only if society were operating fairly would measures that take race, sex, and national origin into account be "preferential treatment." After the commission on civil rights was reorganized in late 1983, however, it took the opposite position. By January of 1984, it approved a statement that "racial preferences merely constitute another form of unjustified discrimination". In recent years, however, affirmative action has continued to grow, and the number of controversies surrounding its existence is consistently augmented. In 1978, in University of California Regents v. Bakke, the U.S. Supreme Court held (5-4) that fixed quotas may not be set for places for minority applicants for medical school if white applicants are denied a chance to compete for those places. The court, however, did say that professional schools may consider race as a factor in making decisions on admissions. More recently than the Regents decision, in United Steelworkers of America V. Weber (1979) and Fullilove v. Klutznick (1980), the court continued to hold for affirmative action. II. An Introduction to the Controversy The transformation of affirmative action o...

List of All Elements Considered to Be Metals

List of All Elements Considered to Be Metals Most elements are metals. This group includes the alkali metals, alkaline earth metals, transition metals, basic metals, lanthanides (rare earth elements), and actinides. Although separate on the periodic table, the lanthanides and actinides are really specific types of transition metals. Heres a list of all the elements on the periodic table that are metals. Alkali Metals The alkali metals are in group IA on the far left side of the periodic table. They are highly reactive elements, distinctive because of their 1 oxidation state and generally low density compared with other metals. Because they are so reactive, these elements are found in compounds. Only hydrogen is found free in nature as a pure element, and that is as diatomic hydrogen gas. Hydrogen in its metallic state (usually considered a nonmetal)​LithiumSodiumPotassiumRubidiumCesiumFrancium Alkaline Earth Metals The alkaline earth metals are found in group IIA of the periodic table, which is the second column of elements. All of the alkaline earth metal atoms have a 2 oxidation state. Like the alkali metals, these elements are found in compounds rather than pure form. The alkaline earths are reactive but less so than the alkali metals. Group IIA metals are hard and shiny and usually malleable and ductile. BerylliumMagnesiumCalciumStrontiumBariumRadium Basic Metals The basic metals display the characteristics people generally associate with the term metal. They conduct heat and electricity, have a metallic luster, and tend to be dense, malleable, and ductile. However, these elements start to display some nonmetallic characteristics. For example, one allotrope of tin behaves more as a nonmetal. While most metals are hard, lead and gallium are examples of elements that are soft. These elements tend to have lower melting and boiling points than the transition metals (with some exceptions). AluminumGalliumIndiumTinThalliumLeadBismuthNihonium: probably a basic metalFlerovium:  probably a basic metalMoscovium: probably a basic metalLivermorium: probably a basic metalTennessine: in the halogen group but may behave more like a metalloid or metal Transition Metals The transition metals are characterized by having partially filled d or f electron subshells. Since the shell is incompletely filled, these elements display multiple oxidation states and often produce colored complexes. Some transition metals occur in pure or native form, such as gold, copper, and silver. The lanthanides and actinides are found  only in compounds in nature.

Depending on conditions, elements belonging to the metalloid group may behave like metals. In addition, even nonmetals may be metals. For example, in certain situations, you may find metallic oxygen or metallic carbon.
