​How many atoms of oxygen are present in one molecule of ozone? ​

Correct option is A

Sol: The correct answer is (a) 3 

Key points:

• One molecule of ozone ( $$O_3$$) contains Three atoms of oxygen.
• ​Ozone is a triatomic molecule, meaning it consists of three atoms.
• The chemical formula for ozone is $$O_3$$​, indicating that each molecule is made up of three oxygen atoms bonded together.

Information booster:

Ozone:

• Ozone $$(O_3)$$​is a gas composed of three oxygen atoms, found mainly in the Earth's stratosphere, forming the ozone layer, which absorbs and blocks harmful UV radiation. At ground level, ozone is a pollutant and a key component of smog. Ozone depletion, caused by CFCs and other chemicals, leads to increased UV exposure, harming ecosystems and health. Efforts like the Montreal Protocol aim to reduce ozone-depleting substances and protect the ozone layer.​
