What is the formula and name of the compound by combining Pb2+ and CrO42-
The Attempt at a Solution
I thought it was Pb2(CrO4)2 - Lead Chromate.
Why is this wrong and how do I correct it?

When writing ionic compounds, you use the smallest number ratio between the ions; you don't always "switch" the charges. Instead of a 2:2 ratio, use a 1:1 ratio for the formula, PbCrO4.
The name is wrong because you need to specify the charge of lead since it has a variable charge.
