6. 1 H 1.00794 Hydrogen Atomic Symbol 1 or 2 letters. The symbol comes from its English or Latin name.

7. Calculating the number of Protons Atomic # = # of Protons Ex: Hydrogen Atomic # = 1 # of Protons = 1

8. Calculating the number of Electrons # of Protons = # of Electrons Ex: Hydrogen # of Protons = 1 # of Electrons = 1

9. Calculating the number of Neutrons Atomic Mass ( rounded to the nearest whole # ) - Atomic # = # of Neutrons Ex: Hydrogen Atomic Mass = 1 Atomic # = 1 1-1 = 0 Hydrogen has no neutrons.
