Answer:

Hope it will help you....

Explanation:

The atomicity of a substance is the number of atoms in each molecule of the substance.

Two molecules of hydrogen and one molecule of oxygen form one molecule of water.

Each molecule of hydrogen has two atoms of hydrogen. Therefore the atomicity of hydrogen is two. Similarly each molecule of oxygen consists of two atoms of oxygen. The atomicity of oxygen is two.

One molecule of water contains two atoms of hydrogen and one atom of oxygen, so the atomicity of water is three.
