Group 1A and 2A elements have the same oxidation number that the ion of the metal would, unless it's in its elemental form. But keep in mind that this is unrealistic. x + 3(-2) = -2. S - 0, elementary sulfur is always 0 SCl2 - +2, Cl is -1 so S has to be +2 SO2 - +4, O is -2 SO3 - +6, the same reason H2SO4 - +6, O is -2, H is +1. Typically, larger elements may have states of oxidation other than those suggested by the group in which they are located. In chemical compounds, an atom's oxidation number refers to the charge that atoms have if the compound consists of only ions. Sulfur: +4 Example: What is the oxidation state of sulfur in SO2? Is the S Oxidized and O is reduced? To find the oxidation number of sulfur, it is simply a matter of using the formula SO2 and writing the oxidation numbers as S = (x) and O2 = 2 (-2) = -4.
