Question

is termed as the number of atoms present in a single molecule of an element.

• A. Atomicity
• B. Molecules
• C. Ions

Answer 1

The correct option is A Atomicity

The number of atoms present in a single molecule of an element is known as atomicity.
For example, oxygen exists as a diatomic molecule which means that a molecule of an oxygen contains two atom hence its atomicity is 2.

Similarly, a phosphorus molecule contains 4 atoms, a sulphur molecule contains 8 sulphur atoms. Hence their atomicity is 4 and 8 respectively.
