Explain characteristics of nuclear binding force

Explanation

Nucleus contains protons and neutrons. The protons in the nucleus experience only the electrostatic force, then the nucleus would fly apart in an instant. There is a strong attractive force between protons to overcome the repulsive Coulomb.s force. This attractive force which holds the nucleus together is called strong nuclear force.
(i) The strong nuclear force is of very short range, acting only up to a distance of a few Fermi, nuclear force is the strongest force in nature.
(ii) The strong nuclear force is attractive and acts with an equal strength between proton-proton, proton-neutron, and neutron - neutron.
(iii) Strong nuclear force does not act on the electrons. So it does not alter the chemical properties of the atom.
