Question

Oxidation number of oxygen atom in O₃ molecules is

• A. 0
• B. +2
• C. +1
• D. -1

Answer 1

The correct option is A

0

Explanation for Correct answer:

Oxidation Number:

• The total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom is known as the Oxidation Number.
• Generally, the Oxidation number is the charge present on the ions.

We know that the Oxygen in the Ozone(${\mathrm{O}}_3$) is all different having -1, 0, and +1 as their oxidation state.

Oxidation state of Oxygen = -1 + 1 + 0

So, the sum of Oxidation states of all the 3 Oxygen will be 0.

Therefore, the Oxidation number of Oxygen atoms in Ozone(${\mathrm{O}}_3$) is 0.
