Atom is a smallest unit which consists of proton , neutron and surrounded by electron.
no of proton is always equal to no of electron and thus atom is no charge
example- H,C,O,N


molecules is combination of atoms with bond .molecule is created by bonded atom when electron fills up the outer orbit of each atom
example - H2, CO2, NO2

The atom is the smallest unit of an element that follows its properties. A molecule is formed when two or more atoms are joined chemically.
