Why do stable nuclei never have more protons than neutrons ?

Text Solution

Verified by Experts

As is known, protons are positively charged and repel eachother electrically. In nuclei with more than 10 protons or so, the force of repulstion becomes too large. Therefore, excess of neutrons is required for stability. This is because neutrons produce only attractive (nuclear) force amongst them.
