Chapter 20, Problem 20.105SP

Interpretation Introduction

(a)

Interpretation:

The given nuclear reaction needs to be balanced.

$\text{A}\text{m + }\text{C}\text{a}\stackrel{}{\to }\text{ ? + 3 }\text{n}$

Concept introduction:

The nuclear reactions are a type of chemical processes which lead to the formation of some new nuclei with the emission of certain particles. Usually alpha or beta particles, or gamma rays are emitted as a side product with some new daughter nuclei. The nuclear reactions follow the conservation of atomic number and mass number of nuclei. It means the sum of mass number on both sides should be same and sum of the atomic number of nuclei should be same on both sides.

Interpretation Introduction

(b)

Interpretation:

The new isotope nuclei formed when $\text{M}\text{c}$ emits one alpha particle needs to be determined.

$\text{M}\text{c }\stackrel{}{\to }?\text{ + }\text{H}\text{e }$

Interpretation Introduction

(c)

Interpretation:

The number of alpha particles that must be emitted to reach $\text{D}\text{b}$ from $\text{M}\text{c}$ needs to be determined.

$\text{M}\text{c }\stackrel{}{\to }\text{D}\text{b + ? }\text{H}\text{e }$
