25/8/2016· Metal, Nonmetal, or Metalloid Lab: Instructions Do NOT write on this paper.Please Return Introduction: Elements have unique physical and chemical properties that make them useful in our everyday lives. Aluminum, for example, is lightweight yet strong
3. Classify each element as a metal, a semimetal, or a nonmetal. If a metal, state whether it is an alkali metal, an alkaline earth metal, or a transition metal. iron …
Features of the Periodic Table Elements that have similar chemical properties are grouped in columns called groups (or families). As well as being nuered, some of these groups have names—for example, alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements).
25/6/2019· Germanium is a rare, silver-colored semiconductor metal that is used in infrared technology, fiber optic cables, and solar cells. Things began to change after 1954, however, when Gordon Teal of Texas Instruments invented a silicon transistor.Germanium transistors

24/3/2020· Zinc is classified as a metal element and is a solid at room temperature. It has a melting point of 787 degrees Fahrenheit, a boiling point of 1,665 F and an atomic weight of 65.38. The element zinc is assigned the nuer 30 on the periodic table of elements, assigned to group nuer 12 and does not have a group name.
Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust
Polonium has a position in the periodic table that could make it a metal, a metalloid or a nonmetal. It is classed as a metal as its electrical conductivity decreases as its temperature rises. Because of this property it is used in industry to eliminate dangerous static electricity in making paper or sheet metal.
