A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number.

From the element table it is clear that an element refers to pure form of substances lik H, He, Li...

Element-> A basic substance that can't be simplified (hydrogen, oxygen, gold, etc).

Atom-> The smallest amount of element.

Molecule-> Two or more atoms that are chemically joined together (H2, O2, H2O, etc).

Compound-> A molecule that contains more than one element (H2O, C6H16O6, etc).
