Chapter 20, Problem 39E

Interpretation Introduction

Interpretation:

Whether the rate of the emission of radiations by uranium after purification is same, less or more than $5000$ counts per minute is to be stated. The explanation for the corresponding answer is to be stated.

Concept introduction:

Any atom which has unstable nucleus due to the presence of more than $1.1$ to $1.5$ neutron to proton ratio value emit harmful radiations to give more stable fragment and these elements are known as radioactive elements. Radioactivity of any element is entirely dependent upon the type of nucleus present in the atom of that element known as nuclear chemical property.
