Not quite. Ag2O
okay thanks...but don't you have to use roman numerals for elements in the "d" block?
That's for NAMING compounds with elements that have multi-valences.
So we would call Fe2O3, iron(III) oxide and
FeSO4 would be iron(II) sulfate.
But silver usually doesn't have a valence other than +1; therefore, I would name Ag2O as silver oxide although I don't know that silver(I) oxide is incorrect. Roman numbers are never used to write a formula as you did.
