Answer:

b. 16 protons, 18 neutrons, and 18 electrons

Explanation:

Things to be remembered

Negative charge on any ionic species indicates gained the electrons

Positive charge on any ionic species indicates lost the electrons

A sulfur atom has 16 protons, 18 neutrons, and 16 electrons, A sulfide ion has a 2– charge which indicates that sulphur has gained two electron from any other atom, ion or species!
