The element fluorine forms a(n) with the charge . The symbol for this ion is , and the name is . The number of electrons in this ion is

A chemical element exhibiting the symbol F and atomic number 9 is fluorine. It prevails as an extremely toxic pale yellow diatomic gas at normal circumstances and is the lightest halogen. It is exceptionally reactive as it reacts with all the other elements except for helium, argon, and neon, and is the most electronegative element.

Fluorine like halogens produces an anion with a charge of -1 to acquire stability. The symbol for this ion is F-, and the name given to the ion is fluoride ion. The atomic number of fluorine is 9, therefore, the number of electrons in this anion is 9+1 = 10.
