  1. An element in group 17 of the periodic table has seven valence electrons. It quickly gains an electron, forming a 1 - anion, which causes it to be highly reactive.
  2. A column of elements in the periodic table having similar valence electron arrangement, resulting in similar chemical properties; also known as a group.
  3. electrons- Any electron in the outermost energy level of a neutral atom. Unpaired valence electrons are usually involved in chemical bonding.
  4. metals- 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.
  5. metals- 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+.
  6. law- The law that states that the properties of the elements vary with their atomic numbers in a regular, repeated pattern.

  1. any electron in the outermost energy level of a neutral atom. unpaired valence electrons are usually involved in chemical bonding.
  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).
  3. an element in Group 2 of the periodic table, having one valence electron that it tends to lose easily to become a 2+ cation, making it very reactive.
  4. 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.
  5. an element in Group 1 of the periodic table, having one valence electron that is can easily lose to form a 1+ cation, making it extremely reactive; the most reactive of all the metals.
Down
  1. a column of elements in the periodic table having similar valence electron arrangement, resulting in similar chemical properties; also known as a group.
  2. See Family
  3. 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.
  4. measure of an element's ability to attract and hold electrons when bonded to other atoms.onDotNotation a representation of an atom consisting of it chemical symbol with surrounding dots representing its valence electron.
  5. a table of the chemical elements arranged to display their periodic properties in relation to their atomic numbers.
  6. 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+.
  7. the law that states that the properties of the elements vary with their atomic numbers in a regular, repeated pattern.
  8. 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.
  9. (1)a row in the periodic table of the elements; also called a series. (2)the time interval (T) for one complete cycle of periodic motion.

14 Clues: See Family • a table of the chemical elements arranged to display their periodic properties in relation to their atomic numbers. • the law that states that the properties of the elements vary with their atomic numbers in a regular, repeated pattern. • ...
