6 Multiple choice questions

  1. the electrostatic force that holds oppositely charged particles together; usually a nonmetal paired with a metal
  2. ion formed from only one atom
  3. an ion made up of two or more atoms bonded together that acts as a single unit with a net charge
  4. States that atoms like hydrogen and helium only need two valence electrons to be stable
  5. an element that can make bonds with more than 8 electrons, able to do so because they all have empty d orbitals
  6. a chemical reaction in which more energy is released that is required to break bonds in the initial reaction
