6 Multiple choice questions

  1. a chemical reaction in which more energy is released that is required to break bonds in the initial reaction
  2. a type of bond that forms when electrons are not shared equally
  3. chemical 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
  4. forms when two or more atoms covalently bond; usually includes two or more nonmetals
  5. the positive or negative charge of a monatomic ion
  6. the electrostatic force that holds oppositely charged particles together; usually a nonmetal paired with a metal

6 True/False questions

  1. chemical bondthe force that holds two atoms together


  2. metallic bondthe attraction of a metallic cation for delocalized electrons


  3. delocalized electronsthe 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


  4. expanded octetan element that can make bonds with more than 8 electrons, able to do so because they all have empty d orbitals


  5. covalent bondthe attraction of a metallic cation for delocalized electrons


  6. duet ruleStates that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons
