Chapter 25, Problem 58A

Interpretation Introduction

Interpretation:

The nuclear reaction taking place in the sun and the nuclear reaction occurring in a nuclear reactor is to be differentiated.

Concept introduction:

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive.

Answer to Problem 58A

The nuclear reaction that takes place in the sun is known as Nuclear Fusion, and that takes place in a nuclear reactor is known as Nuclear Fission.

Explanation of Solution

The nuclear reaction that takes place in the sun is known as Nuclear Fusion and the nuclear reaction that takes place in a nuclear reactor is known as Nuclear Fission

The main difference between the two nuclear reactions is that fission is the process in which a large nucleus is split into two or more nuclei whereas fusion is the process in which two or more nuclei combine or "fuse" to form a large nucleus
