An element is a pure substance that can't be broken down into simpler substances by chemical or physical means. Elements are the fundamental building blocks of matter, and each element is made up of atoms of the same type. Examples of elements include oxygen (O), hydrogen (H), carbon (C), and gold (Au). Each element has its unique set of properties, and it consists of only one type of atom.
