  1. 3. formula: A shorthand way of identifying a chemical compound consisting of the element symbols and subscripts that represent the number of atoms of each element.
  2. 4. The unequal distribution of electric charge in a covalent bond.
  3. 6. rule: The principle that states that atoms generally are most stable when the have eight electrons in their valence energy level.
  4. 7. formula: When compounds are made from two elements.
  5. 10. bond: A chemical bond formed when atoms transfer valence electrons.
  6. 11. unit: The smallest whole number ratio of ions within an ionic compound.
  7. 12. ion: A group of covalently bonded atoms that together have gained or lost electrons and act as a single ionized particle.

  1. 1. bond: The attraction between metal atoms and their collectively shared valence electrons.
  2. 2. molecule: A molecule made of two atoms.
  3. 5. structure: A system for modeling the covalent bonds between atoms in a molecule and any unbonded electrons in the molecule.
  4. 6. state: A positive or negative number showing the electric charge on an element when it forms a compound.
  5. 8. bond: A electrostatic attraction that forms between atoms when they share or transfer valence electrons.
  6. 9. bond: A chemical bond that involves the sharing of electrons to form electron pairs between atoms.
