Show Answers:

  1. Mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together
    Chemical Bond
  2. Chemical bonding that results from the electrical attraction between cations and anions
    Ionic Bonding
  3. Results from the sharing of electron pairs between two atoms
    Covalent Bonding
  4. A covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge
    Non-Polar Covalent Bond
  5. Have uneven distribution of charge
  6. A covalent bond in which the bonded atoms have an unequal attraction for the shared electrons
    Polar Covalent Bond
  7. A Neutral group of atoms that are held together by covalent bonds
  8. A chemical compound whose simplest units are molecules
    Molecular Compound
  9. Indicates the relative numbers of atoms of each kind in a chemical compound by using atomic symbols and numerical subscripts
