Identify the chemical formula given: AgMnO_4. This compound contains silver (Ag) and the permanganate ion (MnO_4^-).
Recall that the permanganate ion (MnO_4^-) has a known charge of -1.
Since the compound AgMnO_4 is neutral overall, the sum of the charges of silver ion (Ag) and permanganate ion (MnO_4^-) must be zero.
Set up the charge balance equation: charge of Ag + charge of MnO_4^- = 0. Substitute the known charge of MnO_4^- as -1, so charge of Ag + (-1) = 0.
Solve for the charge of Ag: charge of Ag = +1. Therefore, the silver ion in AgMnO_4 has a charge of +1.
