How many electrons, protons, neutrons, and what is the atomic number and atomic mass (if any) does Fluoride have?

ExtremeBDS [4]

Fluoride is an anion of Fluorine

What this means is that the two have the same number of protons (9), but Fluoride has 10 electrons compared to Fluorine's 9.

So the answers are:
Protons - 9
Neutrons - 9
Electrons - 10
Atomic Number - 9
Atomic Mass - 19 g/mol
