write the correct formula for the compound listed below:
1. Silver Oxide
my answer: AgIIO
correct?
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.
No, your answer is not correct. The correct formula for Silver Oxide is Ag2O.
To determine the correct formula for Silver Oxide, we need to consider the charges of the ions involved. Silver is a transition metal and typically forms a +1 charge, while oxygen usually forms a -2 charge.
To balance the charges, we would need two silver ions (+1 charge each) to bond with one oxygen ion (-2 charge). This results in the formula Ag2O, where the subscript 2 indicates that there are two silver ions and the subscript O indicates one oxygen ion.
So, the correct formula for Silver Oxide is Ag2O.
