What is the formula unit for a compound made from Pb4+ and oxygen?
1 answer:
Answer : The formula unit of compound will be,
Explanation :
As we know that one atom of oxygen contains (2-) charge and one atom of lead contains (4+) charge. So, to balance the of charges of lead, the 2 oxygen atoms combine with the 1 lead atom. Thus, the compound formed will be, .
That means, when combine with oxygen that is,
