The platinum(II) cation has a 2+ charge, with the formula Pt^2+. The iodate anion has a 1- charge, with the formula IO3^1-. The formula of platinum(II) iodate must be neutral, so one platinum(II) cation and two iodate anions must combine to form Pt(IO3)2.
PtCl2(H2O)2 or PtCl2 • 2H2O. I'm not sure, but I think it's the first...
[PtCl2(H2O)2] is dichlorodiaquoplatinum(II).
Platinum is an inert metal which does not form sulfides. It is possible (but difficult) to form platinum hexafluoride, that is the only known compound of platinum.
Pt3N2 is the formula for platinum (II) nitride.
The formula of platinum IV dichromate is Pt(Cr2O7)2.
Formula: Pt(H2O)2Cl2
Pt2

Lead II oxide is PbO
This oxide has the chemical formula BkO.
Mercuric oxide or mercury (II) oxide : HgO
The chemical formula for silver(I) oxide is Ag2O.The chemical formula for silver(II) oxide is AgO.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
The formula for copper(II) oxide is CuO. This is the commonly met black powder. Copper(I) oxide also exists. This is a red powder, and its formula is Cu2O where the 2 should be a subscript.
