. What does agamma rayrepresent? Is a γ ray a particle? Is there a change in mass or atomic number when a nucleus produces only a γ ray?

Interpretation Introduction

Interpretation:

Interpret gamma ray and identify the effect on atomic number and mass number in gamma decay.

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.

Explanation

Gamma rays having the highest penetrating radiation which obtained from decay of nucleus of an atom as a by product. It is having smallest wavelength and thus having higher energy of penetrating.

A gamma particle contains 0 mass number and 0 number of proton.

A gamma decay is shown below:
