Interpret an example which results in production of original nuclide with two successive decays. Concept Introduction: The decaying of an atom takes place by three type of decay such as alpha decay, beta decay, gama decay. In alpha decay, an alpha particle with mass 4m and electron 2e removed from nuclide while in beta decay two type of decay are possible beta (+) and beta (-). In gamma decay, nuclide will remain same to the original one.

Question

Chapter 19.1, Problem 1CT

Interpretation Introduction

Interpretation:

Interpret an example which results in production of original nuclide with two successive decays.

Concept Introduction:

The decaying of an atom takes place by three type of decay such as alpha decay, beta decay, gama decay.

In alpha decay, an alpha particle with mass 4m and electron 2e removed from nuclide while in beta decay two type of decay are possible beta (+) and beta (-). In gamma decay, nuclide will remain same to the original one.
