Chapter 19, Problem 19.5QP

Interpretation Introduction

Interpretation:

From the given nuclear decay, the one that produces a daughter nucleus with a higher atomic number has to be identified.

Concept Introduction:

In alpha decay ($\alpha$ ) - Mass number decreases by 4 and atomic number decreases by 2

In beta decay (${}_{-1}^0\beta$) - Mass number remains unchanged and atomic number increases by 1

In gamma decay ($\gamma$) - Mass number remains unchanged and atomic number remains unchanged.

In positron emission (${}_{+1}^0\beta$ ) - Mass number remains unchanged and atomic number decreases by 1

In electron capture- Mass number remains unchanged and atomic number decreases by 1
