Metals


 * Metals**


 * Classified by the high level of conductivity.
 * Metals- The majority of the elements are classified as metallic elements, or metals. All elements on the left side and the middle of the periodic table are metals (except Hydrogen).
 * Metals are divided into different groups; the alkali metals in column I, the alkaline earth metals in column II, and the transition metals in columns III through XII.
 * All metals except Mercury are solid at room temperature. Most metals have a very high melting point.
 * Metal physical characteristics: luster, conducts electricity, heat conductivity.
 * Most metals are very reactive and oxidize easily. Elements like iron rust over time. Transition metals take the longest to react with other elements and alkali metals react very quickly. ei: CaO (s) + H20 (l) --> Ca(OH02 (aq)
 * Some metals loose their luster after reacting with oxygen. (Alkali earth metals)
