O is 2- and there are two of them so Pb would have to be 4+
-2 for each O +4 for Pb
oxidation number of I is -1. oxidation number of F is +1.
PbO2 is lead(IV) oxide.
Zn has oxidation number +2; S has oxidation number -2
The oxidation number for H is +1, and the oxidation number for O is -1.
-2 for each O +4 for Pb
Plumbic oxide, is Lead (IV) oxide. It has the formula of PbO2, which is neutral. However if you wanted to know the oxidation state of the lead, then it is +4.
O=-2 Pb=x x+(-2)*2=0 x+4-=0 -4+4=0 Pb4-
