In summary, lead iodide has the formula PbI2 because lead typically has an oxidation state of +2, while iodine only needs to gain one electron to have a stable octet. This is why the formula is not PbI4, which would require lead to have an oxidation state of +4.

**EDIT** Never mind just realized that it is lead(II) in PbI2. Hehe... Awkward
Why does lead iodide have the formula PbI2?
Pb needs to lose (or gain) 4 electrons to have a stable octet and Iodine needs to gain only 1. So why isn't the equation PbI4? It seems like it should be... Please explain if you can.
Thanks :)

Lead is one of those elements with multiple oxidation states (either +2 or +4). The most common state is +2, which is why lead iodide is PbI2
