ncert.nic.inattraction and repulsion between interacting particles (atoms and molecules). This term does not include the electrostatic forces that exist between the two oppositely char ged ions and the forces that hold atoms of a molecule together i.e., covalent bonds. Attractive inter molecular for ces ar e known as van der W aals for ces, in honour of Dutch

Isotopes Isotopes are atoms with the same atomic number but different numbers of neutrons. Many elements consist naturally of mixtures of isotopes, with very similar chemical properties.
