1 Chemistry 2

2 Goal 6  1. Groups, Families  2. Periods, Row  3. Group, Family also same oxidation #  4. Period  5a. Group 1, 1A +1  5b. Group2, 2A, +2  5c Group 3-12  5d. Group 17, 7a, -1  5e. Group 18, 8a, stable

3 Goal 6  6a. Left of stair step line  6b. Right of stair step line  6c. Along the stair step line (semiconductors)  7a. room temp., High melting and boiling points, ductile (pulled into wire), malleable (shaped or flattened into sheets), Good conductors of heat and electricity, shiny luster  7b. Gases or Brittle temp., Low melting and boiling points, poor conductors, good insulators, dull luster.
