The oxidation number of chlorine in the compound PbCl is -1. Each chlorine atom in PbCl has an oxidation number of -1, as lead has a fixed oxidation number of +2.


Why do elements with positive oxidation number easily combined with those having a negative oxidation number?

Elements with positive oxidation numbers have excess electrons that they can share or transfer with elements having negative oxidation numbers that have electron deficiencies. This transfer or sharing of electrons allows the elements to achieve a more stable electron configuration, forming compounds through the formation of ionic or covalent bonds.
