Why do stable nuclei never have more protons than neutrons ?
Why do stable nuclei never have more protons than neutrons ?
Because if no. of protons is more than no. of neutrons then the excess repulsive force produced between the protons can not be counter balanced by less nuclear force between smaller no. of neutrons and so nucleus will become unstable.
