Thinking about Bohr Models…
1.How many electrons can go on the first ring?2.How many electrons can go on the second
ring?3.How many electrons can go on the third ring?

4. How many protons does lithium have?
5. How many neutrons?
6. How many electrons?
7. Draw the Bohr model for lithium.

Use the picture below to check your answers to #7.
If your Bohr model is wrong…go back and change it now!

VALENCE = OUTSIDE
Lithium has 3 total electrons but only 1 VALENCE ELECTRON.
