How Many Protons, Neutrons and Electrons Does Fluorine Have?

Fluorine has nine protons, nine electrons and 10 neutrons. The number of protons and electrons within an atom are always equivalent when an atom is in a stable state. The negatively charged electrons balance out the positively charged protons, rendering the atom electrically neutral.

Fluorine is the most reactive non-metallic element found in nature and is one of the five halogens, a group of highly active non-metallic elements. Owing to its chemically reactive nature, fluorine is not an independently occurring element; it needs to be extracted from a naturally occurring compound containing other elements. Fluorine is most commonly derived from the minerals fluorite, apatite and cryolite.
