Answer

Fluorine has 9 protons, so it will also have 9 electrons. The first and second orbitals will be occupied. The first shell will have two electrons and is full; The second shell has 7 more electrons but needs ONE more to be fill the valence shell and meet the octet rule.

Work Step by Step

All atoms will be neutral in their common/natural state. This means it will have the same number of electrons and protons. The first two electrons will be in the 1S orbital, the next two in the 2S, and the remaining in the 2P orbital.
