Chapter 20, Problem 5PE

Interpretation Introduction

Interpretation:

The balanced nuclear equation for the decay of radium $-226$ is to be written and the particle which is emitted is to be identified.

Concept Introduction:

The nuclear equation must be balanced. In nuclear equations, a change in the nucleus takes place whereas, in chemical reactions, a loss or gain of electrons takes place.

There is a difference between chemical and nuclear reactions. Chemical reactions involve atoms, molecules and electrons whereas, nuclear reactions include the nucleus of an atom.
