Define Atomicity of a Gas

Atomicity of a gas means the number of atoms present in one molecule of that gas.

Every gas molecule is made up of one or more atoms. The atomicity shows how many atoms combine to form one molecule of that gas. It helps scientists understand the molecular structure and behavior of gases.

Types of Gases Based on Atomicity:

Importance:

• Helps calculate molecular mass
• Used in chemical reaction equations
• Explains gas behavior under different conditions

So, atomicity is a simple but key concept in chemistry that tells how many atoms make up one molecule of a gas.
