The amines and amides are organic compounds containing the element

The key feature of an amine is a nitrogen atom bonded to a carbonyl carbon atom. Like esters, amides are formed in a condensation reaction. ... These polymers are formed from another organic nitrogen compound, the amino acid. These molecules contain both an amine group and a carboxyl group.

nitrogen

Explanation:

Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

1. Amides have functional group .

Example: Ethanamide with molecular formula

2. Amines have functional group .

Example: Ethanamine with molecular formula

Thus both amines and amides are organic compounds containing the element nitrogen.
