Chapter 10, Problem 73P

Interpretation Introduction

(a)

Interpretation:

The number protons, neutrons and electrons in strontium-89 needs to be determined.

Concept Introduction:

Radioactive isotopes contain numerous applications. Usually, they are valuable because either one might sense their radioactivity or might utilize the energy released by them. Due to the easy detection of radioactivity of radioactive isotopes, they are effective tracers.

Interpretation Introduction

(b)

Interpretation:

For the emission of a beta particle from strontium-89, the balanced nuclear equation needs to be determined.

Concept Introduction:

Radioactive isotopes contain numerous applications. Usually, they are valuable because either one might sense their radioactivity or might utilize the energy released by them. Due to the easy detection of radioactivity of radioactive isotopes, they are effective tracers.

Interpretation Introduction

(c)

Interpretation:

The mass of strontium-89 is 10.0 $\mu g$ of strontium-89. The mass of radioisotope remaining after 200 days needs to be determined.
