  1. 1. an attraction between atoms that allows the formation of chemical substances that contain two or more atoms
  2. 2. An atom with more or less electrons than protons
  3. 5. drawing that shows valence electron movement between atoms
  4. 6. Number assigned to an element in chemical combination that represents the number of electrons lost
  5. 8. an electron moves from an atom or a chemical species to another atom or chemical species
  6. 9. valence of an ion is the coefficient that, when multiplied by the elementary charge, gives the ion's charge.
