Elements, compounds, and mixtures - Purdue University

Elements. Any substance that contains only one kind of an atom is known as an element.Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P 4) or sulfur (S 8) cannot be broken down into simpler substances by these reactions.. Example: Water decomposes into a mixture of hydrogen and oxygen when an electric current is passed through the liquid.
