Atom is defined as the smallest unit of an element which may or may not exists independently. On the other hand, molecule implies the set of atoms held together by the bond, indicating the smallest unit of a compound.

Atoms may or may not exist in the free state, but molecules exist in the free state.

Atoms comprise of the nucleus (which contains protons and neutrons) and electrons. Conversely, a molecule comprises of two or more, identical or different atoms, combined chemically.

Atoms cannot be further divided into sub-atoms. As against this, molecules can be further divided to individual atoms.

The shape of an atom is spherical whereas the molecules can be linear, angular or rectangular in shape.
