Chapter 24, Problem 44A

Interpretation Introduction

(a)

Interpretation:

If mass number and atomic number are uncharged then to categorize radioactive decay.

Concept introduction:

Radioactive decay is unstable nuclei that lose energy by emitting radiation in a spontaneous process. Until they form stable atoms unstable atoms undergo radioactive decay, often of a dissimilar element.

Answer to Problem 44A

The radioactive decay is gamma radiation.

Explanation of Solution

A high-energy radiation which possesses no mass is gamma radiation. The symbol of gamma radiation is $\text{γ}$. Gamma rays are neutral. They are not covering up by magnetic or electric fields. Usually gamma ray leads alpha and beta radiation, during radioactive decays they account for most of energy lost.

(b)

Interpretation Introduction

Interpretation:

If mass number remains same and atomic number decreases then to categorize radioactive decay.

Concept introduction:

Radioactive decay is unstable nuclei that lose energy by emitting radiation in a spontaneous process. Until they form stable atoms unstable atoms undergo radioactive decay, often of a dissimilar element.

Answer to Problem 44A

The radioactive decay is beta ray.

Explanation of Solution

Beta radiation is cover up toward positively charged plate and consists of fast moving beta particles. Beta radiation consist fast moving beta particles. The symbol of beta particles is $\text{β}$. Negative charge of beta particle explains that it is attracted to positively charged plate.
