Asked Jan 6, 2020

 Rank alpha particles, beta particles, positrons, and gamma rays in terms of: (a) increasing ionizing power; (b) increasing penetrating power. 


Expert Answer

Step 1

The nuclear reactions are a type of chemical processes which lead to the formation of some new nuclei with the emission of certain particles. Usually alpha or beta particles, or gamma rays are emitted as a side product with some new daughter nuclei.

Step 2

Alpha particles are positively charges nucleus of helium with atomic number 2 and mass number 4. It is represented ‘α’ or as given. These particles have least penetrating power but the highest ionization power due to +2 charge compare to gamma rays and beta particles.

Step 3

Gamma rays are charge less and massless rays which are represented as “γ”. These rays ...
