Chapter 25, Problem 89SAE

Interpretation Introduction

Interpretation:

Initial decay rate and final decay rate of a substance is given as $2.00\times {10}^{10}{s}^{-1}$

$6.25\times {10}^8{s}^{-1}$ respectively, the half life is to be calculated.

Concept introduction:

In nuclear reaction, one subatomic particle is bombarded on an atom and decay of parent nuclide starts. Each of the radioactive elements has a definite half life period which indicates the time taken for decaying half of the element.
