Chapter 18, Problem 33E

Interpretation Introduction

Interpretation:

The radionuclide obtained on bombarding $\text{Br-81}$ with gamma rays is to be identified.

Concept introduction:

The elements whose nuclei decay spontaneously are known as radioactive elements. The decay is accompanied by the emission of alpha particles, beta particles, and gamma rays. All the elements which have an atomic number greater than atomic number $83$ are radioactive. Radioactive forms of elements are known as radio nuclides.
