The oxidation number of sulfur in H2S is -2. Here's how you can determine this:

1. Hydrogen usually has an oxidation number of +1. Since there are two hydrogen atoms, the total oxidation number for hydrogen is +2.

2. The sum of oxidation numbers in a neutral compound is zero.

3. Therefore, to balance the +2 from hydrogen, sulfur must have an oxidation number of -2.
