8. tells us the number of atoms of each element in a compound
10. between the oxygen and each hydrogen in a water molecule (H2O)
11. where two pairs of electrons are shared between the atoms rather than just one pair
12. a substance composed of exactly two different elements
13. a chemical compound composed of ions held together by electrostatic forces termed ionic bonding
14. ratio between the amounts in moles of any two compounds involved in a chemical reaction

1. When a covalent bond forms with one pair of shared electrons
2. model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom
3. formed from the attraction between mobile electrons and fixed, positively charged metallic atoms
4. useful tool for determining the precision of your calculations
5. a chemical bond between two atoms involving six bonding electrons instead of the usual two in a covalent single bond
