Structure Smallest particle with properties of an element. Combination of two or more atoms.
Stability An 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 Elements Protons, Electrons & Neutrons Two or more atoms of the same or different elements
Reactivity Except for the noble elements, atoms of all elements showcase a certain level of reactivity. Compared to a molecule, the level of reactivity is less as some of the valence points are filled by electrons of combined elements.
