Question
Chapter 20, Problem 12E
Interpretation Introduction
Interpretation:
“ Magic numbers” should be identified.
Concept introduction:
In any nuclide, neutron to proton ratio (N/Z) is an important factor in determining the overall stability of that particular nuclide. There are certain number of protons and neutrons that give an additional stability to a nuclide. Those number of protons and neutrons are known as magic numbers. There are few isotopes that have magic numbers for both protons and neutrons; this is known as double magic numbers.
These magic numbers are:
• proton: 2, 8, 20, 28, 50, 82, 114
• neutron: 2, 8, 20, 28, 50, 82, 126, 184
