Understand that the sulfate ion is a polyatomic ion composed of sulfur and oxygen atoms with a specific charge.
Recall that the sulfate ion consists of one sulfur atom bonded to four oxygen atoms, giving the formula \(SO_4\).
Recognize that the sulfate ion carries a charge of 2-, which is written as a superscript: \(^{2-}\).
Combine the chemical formula and the charge to write the correct formula for the sulfate ion as \(SO_4^{2-}\).
Compare this formula to the other options to confirm that \(SO_4^{2-}\) is the correct representation of the sulfate ion.
