The simplest pure substances that cannot be broken down into any other substances are elements. Elements are made up of only one type of atom and cannot be separated into simpler substances by ordinary chemical reactions. Examples include hydrogen, oxygen, and carbon.
An element is a substance that cannot be broken down into other substances by chemical or physical means. It consists of atoms with the same atomic number and unique set of properties. Examples of elements include hydrogen, oxygen, and gold.
