Question

Utilisateur supprimé · Answer

The nucleus is unstable if the neutron-proton ratio is less than 1:1 or greater than 1.5.

At close distances, a strong nuclear force exists between nucleons.This attractive force comes from the neutrons.

More protons in the nucleus need more neutrons to bind the nucleus together.
