An element is a matter that can exist either as atoms (e.g. argon) or as molecules (e.g., nitrogen). Elements cannot be broken down into a simpler type of matter by either physical or chemical means, consisting of only one kind of atom. Conversely, a molecule is a group of two or more atoms that are chemically combined.
A compound is a pure substance that contains two or more different elements chemically combined. A compound can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), has properties that are different from its component elements, and always contains the same ratio of its component atoms.
