Expert Answer:

A neutrino is an electrically neutral, weakly interacting elementary subatomic particle with half-integer spin. The neutrino (meaning "small neutral one" in Italian) is denoted by the Greek letter ? (nu).

Neutrinos are produced in radioactive decay like beta decay. They take care of the conservation of energy and momentum in radioactivity reaction. They are highly penetrable.

Neutrino is a neutral particle with an extremely small mass.  Their mass has never been measured accurately.
