Across
  1. 6. Any of groups 13-16 in the periodic table; so named because they contain metals, nonmetals, and metalliods. These groups are often named for the first element in the family
  2. 8. Any electron in the outermost energy level of a natural atom. unpaired valence electrons are usually involved in chemical bonding
  3. 10. The law that states that the properties of the elements vary with their atomic numbers in a regular repeated pattern
  4. 11. An element in group 18 on the periodic table having eight valence electrons that fill the outer energy level
  5. 12. A row in the periodic table of the elements also called a series, the time interval for one complete cycle of periodic motion
  6. 13. A column of elements in the periodic table having similar valence electron arrangement, resulting in similar chemical properties; also known as a group
  7. 15. Any elements in groups 3-12 of the periodic table, typically having one or two valence electrons, which it easily loses, resulting in cations with charges of 1+ or 2+
  8. 16. An element that is typically dense, solid, ductile, malleable, highly conductive, and chemically reactive, especially in the presence of nonmetal elements. Located on the left end of the periodic table
Down
  1. 1. An element in group 2 of the periodic table, having two valence electrons that it tends to lose easily to become a 2+ cation, making it very reactive
  2. 2. An element that typically has four or more valence electrons and that does not exhibit the general properties of metals; located on the right selection that periodic table
  3. 3. Also known as a family
  4. 4. An element with characteristics between those of metals and nonmetals, also called a semi-conductor; located between metals and non-metals on the periodic table
  5. 5. An element from either of two rows usually placed below the periodic table; a ,ember of either the lanthanide or antinide series. it typically has two valence electrons
  6. 7. A table of the chemical elements arranged to display their periodic properties in relation to their atomic number
  7. 9. An element in group 1 of the periodic table, having one valence electronthat it can easily lose to form a 1+ cation, making it extremely reactive; the most reactive of all metals
  8. 14. An element in group 17 of the periodic table having seven valence electron, it easily gains an electron, forming a 1-anion
