The correct answer is
$O_3$

Ozone Chemical Formula Explanation

The question asks for the chemical formula of Ozone.

Identifying the Chemical Formula

Ozone is a molecule composed of three atoms of oxygen. It is an allotrope of oxygen, meaning it's a different structural form of the same element in the same physical state.

Oxygen, as we commonly breathe, exists as a diatomic molecule, denoted by the chemical formula \(O_2\). Ozone, however, is triatomic.

Therefore, the chemical formula representing Ozone, which consists of three oxygen atoms bonded together, is:

  • \(O_3\)

This distinguishes it from elemental oxygen (\(O_2\)).

Conclusion

Based on its composition of three oxygen atoms, the correct chemical formula for Ozone is \(O_3\).
