Answer:
[tex]\boxed {\boxed {\sf +4}}[/tex]
Explanation:
Lead (Pb) has 2 positive oxidation states, +4 and +2.
Sulfur (S) has 3 oxidation states: +6, +4, and -2. Since lead creates a positive ion, sulfur must be a negative ion to balance the charges.
There are 2 atoms of sulfur, each with a charge of -2. Therefore, their overall charge is -4, because 2* -2= -4.
A compound has a net charge of 0. To achieve this, lead must have a charge of +4 to balance out the -4 charge of sulfur.
Lead has a +4 ionic charge in PbS₂
