Number 9 fluorine

Explanation:

An anion is a negatively charged ion. The smallest atom in the group VIIA family is florine. The atoms get larger as the atomic number increases in going down the periodic table, and more shells of electrons are added to the atoms.

Fluorine is the smallest atom in the Group VIIA family, so it is also the smallest negatively charged anion in the family.
