Across
  1. 1. - the 14 elements with atomic numbers from 90 to 103
  2. 8. - elements and/or compounds that when put together are unable to react chemically
  3. 10. - group 13; have 3 valence electrons; both metals and metalloids
  4. 12. - group 2 elements; contain 2 valence electrons making them the second most reactive metals on the periodic table.
  5. 13. - groups 3-12 on the periodic table; have varying numbers of valence electrons and do not follow normal trends of other metals; form brightly colored compounds and ions in solution.
Down
  1. 2. - group 16; 6 valence electrons; also called Oxygen Family
  2. 3. - group 1 elements, except for hydrogen, that are on the left side of the modern periodic table; contain 1 valence electron making them the most reactive metals on the periodic table.
  3. 4. - A group of elements on the periodic table that share common properties
  4. 5. - group 18; 8 valence electrons (He has only 2); have a full valence shell making them very stable and inert; nonreactive
  5. 6. - group 14; 4 valence electrons, composed of 1 nonmetal, 2 metals, 2 metalloids; carbon forms 5 million compounds and is called 'basis of life'.
  6. 7. - group 17; 7 valence electrons; only need 1 valence electron to become stable and they gain this electron easily, making them the most reactive nonmetals on the periodic table.
  7. 9. - group 15; 5 valence electrons, tend to share electrons; nitrogen is the most abundant element in the earth's atmosphere
  8. 11. - The 14 elements with atomic numbers from 58 to 71
