Chapter 19, Problem 19.23P

Interpretation Introduction

Interpretation:

We need to predict the final nucleus after sequential loss of $\text{α}\text{and}\text{β}$ particles.

Concept introduction:

Loss of $\text{α}\text{and}\text{β}$ particles leads to change in mass number and atomic number of parent nucleus.
Loss of 1 $\text{α}$ particle leads to the reduction in mass number (A) by 4 and reduction in atomic numbers (Z) by 2.
Loss of 1 $\text{β}$ particle leads to the reduction in atomic number (Z) by 2 while mass number remains same.
