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.

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 substance that cannot be broken down chemically into other substances is called an element. Elements are the fundamental building blocks of matter and consist of atoms, which are defined by the number of protons in their nuclei. Each element has unique properties and cannot be decomposed into simpler substances through chemical reactions. Examples of elements include hydrogen, oxygen, and gold.

That would be an Element.
A pure substance that cannot be chemically broken down into simpler substances.
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.
