  1. An element in Group 17 of the periodic table having seven valence electrons. It easily gains an electron, forming a 1 − anion, which causes it to be highly reactive.
  2. An element in Group 18 on the periodic table having eight valence electrons that fill the outer energy level. (Helium is an exception with only two.) With a full outer energy level, it is inert (i.e., nonreactive).

  1. The law that states that the properties of the elements vary with their atomic numbers in a regular, repeated pattern.
  2. Any electron in the outermost energy level of a neutral atom. Unpaired valence electrons are usually involved in chemical bonding.
  3. An element in Group 18 on the periodic table having eight valence electrons that fill the outer energy level. (Helium is an exception with only two.) With a full outer energy level, it is inert (i.e., nonreactive).
  4. An element from either of two rows usually placed below the periodic table; a member of either the lanthanide or actinide series. It typically has two valence electrons.
  5. The distance from the center of an atom’s nucleus to its outermost energy level.
  6. Any of Groups 13–16 in the periodic table; so named because they contain metals, nonmetals, and metalloids. These groups are often named for the first element in the family.
  7. An element with characteristics between those of metals and nonmetals; also called semiconductors; located between metals and nonmetals on the periodic table.
  8. 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.
  9. A measure of an element’s ability to attract and hold electrons when bonded to other atoms.
