검증된 단계별 안내1
Identify the central atom in the polyatomic ion. In this case, the central atom is arsenic (As).
Determine the oxidation state of the central atom. For AsO4^{2-}, arsenic is typically in the +5 oxidation state.
Recognize the number of oxygen atoms bonded to the central atom. Here, there are four oxygen atoms.
Understand the naming convention for oxyanions. When the central atom is in its highest oxidation state, the suffix '-ate' is used.
Combine the central atom name with the appropriate suffix. Since arsenic is in its highest oxidation state with four oxygens, the name is 'arsenate'.
