Element
An element is a substance that cannot be broken down into simpler substances with all the characteristics of that element. Elements are composed of only one type of atom and they cannot be chemically decomposed into simpler substances.
A chemically pure substance is a substance that cannot be separated expect by chemical means. For instance, water can be broken down by electrolysis into oxygen and hydrogen. Yet, it is still a pure substance because a chemical change must occur in order for this to happen.

A pure substance that cannot be broken down into simpler substances by physical or chemical means is an element. This is because Elements can't be broken down chemically into other substances because there is nothing to break them down into.
An element is a substance that cannot be broken down chemically into simpler substances. Each element is made up of atoms that have the same number of protons in their nucleus, distinguishing them from all other elements. Examples include oxygen, carbon, and gold.
