Chapter 14, Problem 14.93PAE

Interpretation Introduction

Interpretation:

The equations for the radioactive decay of radium and radon should be written.

Concept Introduction:

The radioactive decay depends on the N/Z value of the nuclei. The nuclei, beyond Z=83, is unstable and undergoes an alpha radioactive decay. The nuclei having N/Z ratio above the stability band shows positron emission or electron capture. The nuclei having N/Z ratio below the stability band shows beta decay.

Here, the N/Z ratio is the ratio of number of neutrons and atomic number.
