Lizbeth Braun · Answer 2

ammonia cannot be an element

Explanation:

An element is the smallest unit of a substance, capable of independent existence and cannot be broken down into smaller units. All the atoms in an element are exactly the same.

Ammonia cannot be an element since it can be broken down to give two different gases with different atomic compositions, each of which is a pure substance.
