Chapter 21, Problem 21.52QP

Interpretation Introduction

Interpretation:

The significance of the even number of protons and neutrons in this case should be explained.

Concept Introduction:

Pauli Exclusion Principle:

Its states that ’No two electrons in atoms can have identical set of four set quantum number’.

I.e. it may be 3 identical but it differ from 4^th one must be differ. As an orbital can contain a maximum of only two electrons and the two electrons must have opposite spins.

The maximum number of electron in s subshell is 2, p subshell is 6 d subshell is 10 and f subshell is 14.

To determine: the significance of the even number of protons and neutrons for the given case.
