MCQ
A free neutron decays into a proton, an electron and
  • A
    A neutrino
  • An antineutrino
  • C
    An alpha particle
  • D
    A beta particle

Answer

Correct option: B.
An antineutrino
b
$_0{n^1}{ = _1}{p^1}{ + _{ - 1}}{e^0} + \bar \nu $
Antineutrino is required for conservation of spin.
