- Atomicity of Oxygen in Ozone (O₃) - The atomicity refers to the number of atoms of the element present in one molecule of a compound. In the case of ozone (O₃), the molecule consists of three oxygen atoms, so the atomicity of oxygen in ozone is 3.
Explanation:
The molecule of ozone (O₃) consists of three oxygen atoms bonded together. Therefore, the atomicity of oxygen in ozone is 3, as there are three oxygen atoms in one molecule of ozone.
