DefinitionMost fundamental and smallest part that can exist of an element.Two or more atoms chemically bonded together.

ExampleOxygen – O

Phosphorus – P

Sulphur – S

Hydrogen – HOxygen – O2

Phosphorus – P4

Sulphur – S8

Water – H2O

StructureThe smallest particle with properties of an element.Combination of two or more atoms.

StabilityAn atom may not always be stable in nature due to the presence of electrons in the outer shells.Molecules are formed to attain stability.

Constituent ElementsProtons, Electrons & NeutronsTwo or more atoms of the same or different elements

ReactivityExcept for the noble elements, atoms of all elements showcase a certain level of reactivity.Compared to a molecule, the level of reactivity is less than some valence points are filled by electrons of combined elements.
