6 Multiple choice questions

  1. a bond that results from the sharing of valence electrons
  2. a mixture of elements that has metallic properties
  3. the simplest ratio of ions represented in an ionic compound
  4. a type of bond that forms when electrons are not shared equally
  5. the positive or negative charge of a monatomic ion
  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. Lewis structureStates that atoms like hydrogen and helium only need two valence electrons to be stable

          

  2. monatomic ionan ion made up of two or more atoms bonded together that acts as a single unit with a net charge

          

  3. endothermica chemical reaction in which more energy is released that is required to break bonds in the initial reaction

          

  4. moleculeforms when two or more atoms covalently bond; usually includes two or more nonmetals

          

  5. 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

          

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