Question

Explain:-

1)Neutrino
2)Positron

Answer 1

A neutrino is a fermion that interacts only via the weak subatomic force and gravity. The mass of the neutrino is much smaller than that of the other known elementary particle

Symbol: v̅e, ντ, v̅μ, v̅τ, νμ, νe

 positron or antielectron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1 e, a spin of 1/2, and has the same mass as an electron

Answer 2

Neutrino and positron are sub-atomic particles present in the atom
