Understand that the sulfide ion is derived from the sulfur atom by gaining electrons to achieve a stable electron configuration.
Recall that sulfur is in group 16 of the periodic table and typically gains two electrons to complete its octet.
Recognize that gaining two electrons results in a net charge of 2- because electrons carry a negative charge.
Express the charge of the sulfide ion as \(S^{2-}\), indicating it has two extra electrons compared to the neutral sulfur atom.
Therefore, the charge of the sulfide ion is 2-.
