What is the formula unit for a compound made from lead (pb4+) and sulfur (s)?

The chemical formula for the compound formed will be

Explanation:

Lead is the 82th element of the periodic table having electronic configuration of

This element has an oxidation state of +4 units.

Sulfur is the 16th element of the periodic table having electronic configuration of

This element requires 2 electrons and thus shows an oxidation state of -2 units.

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Thus, the chemical formula for the compound formed will be

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
