Across
  1. 3. Has properties of both metals and nonmetals.
  2. 5. Family of metals with two valence electrons, Group 2.
  3. 6. Energy needed to remove an electron; increases across a period.
  4. 10. Family of metals with one valence electron, very reactive metals in Group 1.
  5. 11. Good conductor, malleable, tends to lose electrons.
  6. 12. Top row of inner transition metals, shiny and reactive.
  7. 14. Group 18, nonreactive due to full valence shells.
  8. 15. Bottom row of inner transition metals, mostly radioactive.
Down
  1. 1. A vertical column on the periodic table.
  2. 2. Ability of an atom to attract electrons in a bond.
  3. 4. Block of metals in the middle of the table, variable charges.
  4. 7. Poor conductor, brittle, tends to gain electrons.
  5. 8. Group 17 elements, very reactive nonmetals.
  6. 9. Distance from nucleus to outermost electron; increases down a group.
  7. 13. A horizontal row on the periodic table.
