Chapter 17, Problem 2SAQ

Interpretation Introduction

Interpretation: The nuclear equation which accurately represents the beta decay is to be identified from the given four options.

Concept Introduction: In case of a beta decay, the atomic number of the product increases by 1 unit. This is because the beta particle has mass number 0 and charge $-1$ and implies the release of an electron. Applying this concept, we can easily figure out which of the given options has more atomic numbers by the respective desired units.

In beta decay there is gain in the atomic number with the same mass number
