Chapter 21.6, Problem 5PE

Interpretation Introduction

Interpretation: The half life of two radioactive isotopes of bismuth is given. If initial amount of sample of each isotope is $\text{25}\text{.0}\text{mg}$, then the amount of each sample remaining after $\text{24}\text{h}$ is to be calculated.

Concept introduction: A process through which an unstable nuclide loses its energy due to excess of protons or neutrons is known as radioactive decay.

To determine: The amount of each sample remaining after $\text{24}\text{h}$ if initial amount of sample of each isotope is $\text{25}\text{.0}\text{mg}$.
