The oxidation state of Chromium (Cr) in Cr2O3 can be determined using the rule that the sum of the oxidation states in a neutral compound is zero.

1. We know that the oxidation state of Oxygen (O) is typically -2.
2. In Cr2O3, there are 3 Oxygen atoms, so the total oxidation state contributed by Oxygen is -2 * 3 = -6.
3. Since the total oxidation state in the compound must be zero, the total oxidation state contributed by the 2 Chromium atoms must be +6 (because +6 + (-6) = 0).
4. Therefore, the oxidation state of each Chromium atom is +6 / 2 = +3.

So, the oxidation state of Chromium (Cr) in Cr2O3 is +3.
