Question

Stability of a nucleus depends upon $n/p$ ratio.

• A. True
• B. False

Answer 1

The correct option is A True

If number of neutrons is plotted against the number of protons, the stable nuclei lie within well-defined region called zone of stability. All the nuclei falling outside this zone are invariably radioactive. Nuclei that fall above the stability zone region has an excess of neutrons while those lying below have more protons. These nuclei attain stability by making adjustment in n/p ratio.
