Question

The number of atoms contained in a molecule of an element is called its atomicity.

• A. True
• B. False

Answer 1

The correct option is A True

Molecule: A molecule is formed when two or more atoms of the same element or different elements are combined together in whole numbers.

Atomicity: Atomicity is the total number of atoms in a molecule.

• Each molecule Nitrogen$\left({\mathrm{N}}_2\right)$is composed of two Nitrogen atoms.
• Hence the atomicity of Nitrogen is 2
• Atomicity of Nitrogen is 2, so Nitrogen is a diatomic molecule.
• The molecules of elements can be monoatomic, diatomic, triatomic, and so on, depending on the number of atoms in each molecule of the element.

Thus, the given statement is True. i.e., The number of atoms contained in a molecule of an element is called its atomicity.
