An element is a chemical substance that cannot be broken-down into any simpler substances by chemical reactions. It consists of only one type of atom, though the atoms of an element may, or may not, join together to form molecules (that depends on the particular element and so the structure of its atoms).he main classifications of matter include the categories element and compound, either of which may also be called a substance (which is a less specific term), and mixture-of which there are also many sub-categories.
