28. Describe the difference between an element and a compound. Give two examples of each. You may use a drawing in your answer.

An element is a pure substance. Simply look at the periodic table for examples of elements. Some examples are oxygen, carbon, and hydrogen.

A compound is composed of two or more elements. Some examples include water (hydrogen and oxygen combination) and carbon dioxide (carbon and oxygen combination).

Compounds can be separated by chemical means, while elements cannot be further broken down (because they are pure)
