(2) beta particle (4) positron



Answer :

(3)- gamma ray has no charge and no mass

Answer:  Gamma ray

Explanation:  Nuclear Emission explains the release of energy stored in the nucleus of an atom in the form of particles like alpha particles, beta particles, gamma ray etc.

Alpha particles are the helium atom having +2 charge.

Beta particles have -1 charge thus beta particle and the electron are same.

Positron has a charge of +1 electron having 1/2 spin.

Gamma rays are the rays which are neutral and have no mass.
