6 Multiple Choice Questions

  1. a model that uses electron-dot structures to show how electrons are arranged in molecules
  2. the electrostatic force that holds oppositely charged particles together; usually a nonmetal paired with a metal
  3. an element that can make bonds with more than 8 electrons, able to do so because they all have empty d orbitals
  4. the electrons involved in metallic bonding that are free to move easily from one atom to the next throughout the metal and are not attached to a particular atom
  5. forms when two or more atoms covalently bond; usually includes two or more nonmetals
  6. an ion made up of two or more atoms bonded together that acts as a single unit with a net charge

6 True/False Questions

  1. oxidation numberthe positive or negative charge of a monatomic ion

          

  2. exothermicchemical reaction in which a greater amount of energy is required to break the existing bonds in reactants than is released when the new bonds form in product molecules

          

  3. metallic bonda bond that results from the sharing of valence electrons
