  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. a model that uses electron-dot structures to show how electrons are arranged in molecules
  4. 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

6 True/False Questions

  1. expanded octeta chemical reaction in which more energy is released that is required to break bonds in the initial reaction

          

  2. chemical bondthe electrostatic force that holds oppositely charged particles together; usually a nonmetal paired with a metal

          

  3. duet ruleStates that atoms like hydrogen and helium only need two valence electrons to be stable

          

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

          

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

          

  6. 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
