Chapter 15, Problem 17QP

Interpretation Introduction

Interpretation:

The product of alpha emission by $\text{R}\text{a}$ is to be determined.

Concept Introduction:

Radioactivity refers to the spontaneous emission of radiation. The unstable atoms give up excess energy through radioactive decay in the form of radiation to form more stable atoms.

There are different types of radioactive decay and one of them is alpha decay. In alpha decay, nucleus emits an alpha particle. The resulting nucleus has atomic number reduced by two units and mass number reduced by four units.
