Use atomic structure to explain why the atomic radius of lithium is larger than the atomic radius of fluorine. 

Both Li and F have two occupied energy levels. However, since F has more protons than Li, F has a greater effective nuclear charge. Therefore, F will have a greater force of attraction between the nucleus and the electron cloud, making its atomic radius smaller than Li.
