Drawing an Atom

6. Electron Shells
1st level holds only 2 electrons

7. Electron Shells 2nd level can hold only 8 electrons
1st level must be full to move on to level 2

8. Electron Shells 3rd level hold up to 18 electrons
2nd level must be full to move to level 3

9. Drawing an Atom
Use the periodic table to find the following information:
