Question

Why is binding energy of nucleon is true representative of stability of atom?

Answer 1

Explanation:

The principal factor for determining whether a nucleus is stable is the neutron to proton ratio. The graph below is a plot of the number of neutrons versus the number of protons in various stable isotopes. Stable nuclei with atomic numbers up to about 20 have an n/p ratio of about 1/1

Answer 2

Explanation:

The binding energy per nucleon of a nucleus is the binding energy divided by the total number of nucleons. Measure of stability of the nucleus. Larger the binding energy per nucleon, the greater the work that must be done to remove the nucleon from the nucleus, the more stable the nucleus.
