Answer 2

$NH_3$ has a atomicity of four.

Explanation:

Atomicity is defined as the number of atoms that are present in the molecule of the compound.

To find atomicity of a given compound , we count the total number of atoms in it.

a) $H_2O$ is made up of 2 atoms of hydrogen and 1 atom of oxygen.Thus, the atomicity is 3.

b) $NH_3$ is made up of 1 atom of nitrogen and 3 atoms of hydrogen.Thus, the atomicity is 4.

c) $CH_4$ is made up of 1 atom of carbon and 4 atoms of hydrogen.Thus, the atomicity is 5.

d) $CO_2$ is made up of 1 atom of carbon and 2 atoms of oxygen.Thus, the atomicity is 3.
