The IV in lead IV oxide means that the lead ion has a 4+ charge. The oxide ion has a 2- charge. The charges must cancel out to zero, so there are 2 oxide ions for every 1 lead â¦ IV ion, which is what the formula PbO2 shows.
What is the formula for Tin IV chromate? Sn(CrO4)2 Tin 4 means that the tin is a cation with a +4 charge. Chromate is a polyatomic ion with the formula (CrO4)-2. Since the tin ion has a +4 charge in this case, andâ¦ the chromate ion has a -2 charge, there is a 1:2 ratio of tin ions to chromate ions.
