Understanding Oxidation States

* Oxidation state is a hypothetical charge an atom would have if all its bonds were 100% ionic.

* Rules for assigning oxidation states:

* The oxidation state of a free element (like O₂ or F₂) is always 0.

* The oxidation state of oxygen is usually -2, except in peroxides (like H₂O₂) where it's -1.

* The sum of oxidation states in a neutral molecule is 0.

Calculating the Oxidation State of Fluorine in O₂F₂

1. Oxygen's oxidation state: Oxygen in O₂F₂ is not in a peroxide, so it has an oxidation state of -2.

2. Total oxidation state of oxygen: There are two oxygen atoms, so their total oxidation state is 2(-2) = -4.

3. Fluorine's oxidation state: Since the molecule is neutral, the sum of the oxidation states must be zero. To balance the -4 from oxygen, each fluorine atom must have an oxidation state of +2.

Therefore, the oxidation state of fluorine in O₂F₂ is +2.
