Question

It has been found that nuclides with `2,8,20,50,82,` and `126` protons or neutrons are exceptionally stable. These numbers are refferd to as the magic numbers and their existance has led to.
A. the idea of periodictiy in nuclear properties similar to the periodicity of chemical elements in periodic table
B. the so-called 'liquid drop model of the nucleus'
C. the so-called 'shell model of the nuclus'
D. have a conveninet exploanation of 'nuclear fission'

Answer 1

Correct Answer - a,c
The idea of magic number has led to the shell model and the nuclides with these number of protons or neutrons have been compared with the inert gases vis-à-vis-à-vis stabitity in terms of clossed shells.
