Chapter 20, Problem 9RQ

Interpretation Introduction

Interpretation:

The composition of the alpha particle, beta particle, positron, and deuteron are to be given.

Concept Introduction:

Radioactive substances are those substances which produce electromagnetic radiations or particles due to an unstable nucleus.

With the decrease in radionuclides, the intensity of the radiations also decreases.

An alpha particle is denoted by ${}_{\text{2}}^{\text{4}}\text{He}$ and bears a charge of $+2$.

A beta particle is signified by ${}_{-1}^0\text{e}$ and consists of $-1$ charge.

A positron is characterized as ${}_1^0\text{e}$. The charge it bears is positive.

A deuteron contains one proton and one neutron.
