Question

What is the atomicity of ozone?

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

The correct option is D

3

The explanation for the correct option:

Option D

Atomicity:

• The number of atoms present in a molecule of an element is called atomicity.
• Depending upon the atomicity, molecules can be monoatomic (He), diatomic(O₂), triatomic (O₃) or polyatomic (S₈).
• The molecular formula of ozone is O_3.
• It is a triatomic molecule which means ozone contains three atoms of oxygen.

Therefore, option D is correct.
