  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. Solid@ 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 solids @room temp., Low melting and boiling points, poor conductors, good insulators, dull luster.
