Answer

Charge: -2

Work Step by Step

Atoms of elements want to have the electron configuration of the nearest noble gas (in terms of number of electrons) on the periodic table. The nearest noble gas to Sulfur (S) is Argon, which is two to the right of Sulfur on the periodic table. In order to get the electron configuration of Argon, Sulfur must gain two electrons, thus giving its most stable ion a charge of -2.
