  1. 1. what we call atoms that stick together on both sides of the equation (ex: PO4, SO3, OH)
  2. 2. we can change this number while balancing equations
  3. 4. what we call the group of these 7 molecules: H2, N2, O2, F2, Cl2, Br2, I2
  4. 5. what we call elements and compounds on the left side of the arrow
  5. 7. small number we cannot add, take away or change when balancing equations
  6. 8. A+B yields AB
  7. 10. what we call elements and compounds on the right side of the arrow
