Question

Heavier nuclides require greater number of neutrons (than protons) to attain stability. Justify.

Answer 1

• The heavier nuclides with the increasing number of protons lead to large coulombic repulsions.
• Increased number of neutrons will separate the protons within the nuclei, which will impart stability. Thus, in order to attain stability heavier nuclide need more number of neutrons.
