Question

What is the formula unit for a compound made from Pb4+ and oxygen?

Answer 1

Pb02

Step-by-step explanation:

guy above was correct i just took my test

Answer 2

Answer : The formula unit of compound will be,
`PbO_2`

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,
`PbO_2`.

That means, when
`Pb^(4+)` combine with oxygen that is,
`O^(2-)`, it gives
`PbO_2` by the criss-cross method.

Criss cross method : It is a method of determining the chemical formula.

The formula unit is a shown below.
