What Are Two or More Elements That Are Chemically Combined?

A molecule is made up of two or more atoms of the same element or compound, or different elements or compounds, that are chemically bound together. A molecule is a quantity of a substance that can be measured by a chosen unit. Molecules are extremely small particles.

Molecules are made up of elements. An element consists of one kind of atom only. An element cannot be broken down into a simpler matter by a chemical or a physical mean. Elements exist as either molecules or atoms. An example of an element molecule is nitrogen. An example of an element atom is argon.
