Chapter 18.2, Problem 18.1PSP

(a)

Interpretation Introduction

Interpretation:

Equation for the conversion of isotope of neptunium to isotope of protactinium by emission of an alpha particle has to be written.

Concept Introduction:

Alpha particle emission results in formation of product nucleus that has mass number reduced by 4 and atomic number reduced by 2.  Alpha particle is represented as $\text{H}\text{e}$.

(b)

Interpretation Introduction

Interpretation:

Equation for the conversion of sulfur-35 to isotope of chlorine by emission of beta particle has to be written.

Concept Introduction:

Beta particle emission results in formation of product nucleus that has no change in mass number but atomic number is increased by 1.  Beta particle is represented as $\text{e}$.
