The nuclear particle having no mass and no charge, but only spin is Correct Answer Neutrino

Neutrinos do not carry electric charge, and have mass quite small, though non-zero. Their mass is tiny even by the standards of subatomic particles. They are electrically neutral, weakly interacting elementary subatomic particles with half-integer spin.
