Understand the definitions of the terms: An element is a pure substance consisting of only one type of atom and cannot be broken down into simpler substances by chemical means.
A compound is a substance formed when two or more elements are chemically bonded together and can be broken down into simpler substances (elements) by chemical reactions.
A mixture is a physical combination of two or more substances (elements or compounds) that can be separated by physical means and does not have a fixed composition.
A solution is a homogeneous mixture where one substance (solute) is dissolved in another (solvent), and it can be separated into its components by physical methods.
Therefore, the only option that cannot be chemically broken down into simpler substances is an element.
