Ion for fluorine
Web22 nov. 2024 · A fluoride ion is an atom with 9 protons in its nucleus, making it a fluorine atom. It is an “ion” because the number of electrons is not equal to the number of protons, which is also the reason for the “ide” suffix. More specifically, each fluoride ion has 10 electrons, giving it a net electrical charge (also known as a valence) of -1.
