Question

atom
ion
+1+2+3-1-2-3

Explanation:

Step1: Determine the charge of fluorine atom

Fluorine atom ($F$) is neutral, so its charge is $0$.

Step2: Determine the charge of fluorine ion

Fluorine is in group 17 of the periodic table. It gains one electron to achieve a stable electron configuration. When an atom gains an electron, it forms a negatively - charged ion. The charge of a fluorine ion ($F^-$) is $- 1$.

Answer:

The charge of the fluorine atom is $0$, and the charge of the fluorine ion is $-1$.
