Question

What is the process of predicting the type of Radioactivity?

Expert Solution
Introduction

Some atomic nuclei are energetically unstable. The rapid disintegration of such unstable nuclei into energetically stable nuclei is termed as radioactivity. It is a highly exoergic reaction where a small mass is converted to energy.

Explanation

The type of radioactive decay can be predicted as follows

If Z>82( too heavy) : alpha decay

If N/Z is very high(excess neutrons) : beta decay

If N/Z is very small(excess protons) : positron emission or electron capture
