Nucleus will be stable generally for neutron-proton ratio value

When a beta^(-) particle is emitted from a nucleus, the neutrons-proton ratio:

When a beta^(-) particle is emitted from a nucleus, the neutrons-proton ratio:

For a nucleus to be stable, the correct relation between neutron number N and proton number Z is.

For a nucleus to be stable, the correct relation between neutron number N and proton number Z is.

What is the effect on neutron to proton ratio in a nucleus when (i) an electron, (ii) a positron is emitted?

Assertion : Generally heavy nuclei are unstable. Reason : It has more neutrons and protons.

All nuclei consist of two types of particles- protaon and neutrons. Nuclear force is the strongest froce. Stability of nucleus is determined by the neutron - proton ratio or mass defect or binding energy per nucleus or packing fraction. Shape of nucleus is calculated by quadrupole moment. Spin of nucleus depends on even or odd mass number. Volume of nucleus depends on the mass number. Whole mass of the atom (nearly 99 % ) is centered at the nucleus. Magnetic moment of the nucleus is measured in terms of the nuclear magnetons. Volume (V) of the nucleus is related to mass number (A) as
