KEY: Bohr Models
Directions: Use the periodic table to determine the correct number of protons, neutrons, and electrons in each atom. Write the number of P and N in the nucleus and draw the correct number of electrons on each energy level. The energy levels are: (2, 8, 18, 32, 50, 72). Many times an energy level will be satisfied with eight electrons. Place a happy or sad face next to each atoms to show its status as an atom.

Na
- Fluorine

- Chlorine
Cl
- Argon
Ar
- Copper
Cu
Protons: The Atomic Number Neutrons: Subtract the Atomic Mass and the Atomic Number Electrons: The Atomic Number because the number of positive charges (protons) equals the number of negative ones (electrons).
