Question
Ammonia is a colourless gas that is used to make fertilizers, cleaners and medicines. A chemist heats up some pure ammonia to very high temperature and finds that it breaks down into two other gases.Is ammonia an element? Explain your answer.
Solution
No, ammonia is not an element. It is a compound. The reason is that it can be broken down into two other gases, namely nitrogen and hydrogen. Elements are pure substances that cannot be broken down into simpler substances by chemical means. Since ammonia can be broken down into simpler substances, it is not an element.
