Its PbCrO4.
When u say Pb(II), it means its valency is +2
And CrO4 also has a valency of -2
So both satisfy their valency needs and form a covalent bond.
As both have a valency of 2, they get cancelled :-
(Pb)2(CrO4)2 becomes PbCrO4.

PbCrO4
the II indicates a +2 ion will be formed, and the CrO4 is -2, so it's a 1:1 bond

PbCrO4, lead chromate, its yellow in colour, n insoluble in water. It is tested by ppt with HCl( of PbCl2) n cromyl chloride test (for presence of chromate ion)
