The polyatomic ion chromate is CrO4-2 and silver cations usually exist as Ag+1. The proper chemical formula for silver chromate is Ag2CrO4. However, Ag is known to exist as the Ag+2 and Ag+3 ions, and there are plenty of Ag+2 compounds that are commercially available. Therefore, silver chromate should be named Ag(I) chromate in my opinion to avoid any confusion since I've seen silver chromate incorrectly written as AgCrO4.
Ag2CrO4 is the molecular formula for silver chromate.
