Which of the following is a correct statement?

A

Beta rays are same as cathode rays

B

Gamma rays are high energy neutrons

C

Alpha particle are singly ionized helium atoms

D

Protons and neutrons have exactly the same mass.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Both the `beta-`rays and the cathode rays are made up of electrons. `gamma-`rays are `EM` waves. `alpha-`particles are doubly ionized helium atoms and protons and neutrons have approximately the same mass.
