Question

Nuclides with even even nucleons are more stable. why?

Answer 1

we all know that our environment is very necessary for our healthy existence on the earth. A healthy environment depends on the good habits of human beings and the circumstances we create. Human, animal, plants, earth and environment are indirectly connected to each other and necessary for the existence of healthy life here.

However, by any means if our environment gets affected negatively, creates lots of problems and many challenges in living a simple and healthy life. Our environment acts as a natural world for us and provides a protection to us from the natural calamities. However, it becomes helpless in protecting us if we disturbs its natural cycle and force it to harm us.

Answer 2

In nuclear physics, properties of a nucleusdepend on evenness or oddness of its atomic number Z, neutron number N and, consequently, of their sum, the mass numberA. Most notably, oddness of both Z and Ntends to lower the nuclear binding energy, making odd nuclei, generally, less stable. This effect is not only experimentally observed, but is included to the semi-empirical mass formula and explained by some other nuclear models, such as nuclear shell model. This remarkable difference of nuclear binding energy between neighbouring nuclei, especially of odd-A isobars, has important consequences for beta decay.

Also, the nuclear spin is integer for all even-Anuclei and non-integer (half-integer) for all odd-A nuclei.
