Explanation:
Detailed explanation-1: -The net charge on a sulfide ion, S2, is 2.
Detailed explanation-2: -A sulfur atom is neutral and has no charge. But in becoming the sulfide anion, the neutral atom gained two negatively charged electrons. This means that the sulfide anion must have a charge of two minus.
Detailed explanation-3: -Thus, the number of electrons in S2− ion is (16+2) that is 18. Hence, S2− ion has 16 protons, 16 neutrons and 18 electrons.
