6 Multiple choice questions

  1. ion formed from only one atom
  2. 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
  3. the positive or negative charge of a monatomic ion
  4. the attraction of a metallic cation for delocalized electrons
  5. the electrostatic force that holds oppositely charged particles together; usually a nonmetal paired with a metal
  6. a chemical reaction in which more energy is released that is required to break bonds in the initial reaction

6 True/False questions

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

          

  2. delocalized electronsan element that can make bonds with more than 8 electrons, able to do so because they all have empty d orbitals

          

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

          

  4. polar covalenta type of bond that forms when electrons are not shared equally

          

  5. formula unitthe simplest ratio of ions represented in an ionic compound
