Wish cannot be separated into simpler substances

Explanation:

An element is a substance that consists of only same type of atoms.

For example, a piece of aluminium metal contains only atoms of aluminium.

An element can never be separated into simpler atoms or substances.

On the other hand, a compound is a substance that contains different atoms which are combined chemically in a fixed ratio by mass.

For example, KCl is a compound and it can be broken down into toms of potassium and chlorine.

Thus, we can conclude that an element cannot be separated into simpler substances.
