Question

Atomicity is defined as the number of atoms joined together to form a molecule of an element.

• A. True
• B. False

Answer 1

The correct option is A True

Atomicity: Atomicity is defined as the total number of atoms present in a molecule of an element.

For example

• Each molecule of $\mathrm{Nitrogen}\left({\mathrm{N}}_2\right)\mathrm{gas}$ is composed of two $\mathrm{Nitrogen}\left(\mathrm{N}\right)$ atoms.
• Hence the atomicity of $\mathrm{Nitrogen}\left({\mathrm{N}}_2\right)\mathrm{gas}$ is 2.
• It is a diatomic molecule.

Thus, the given statement is True. i.e., Atomicity is defined as the number of atoms joined together to form a molecule of an element.
