Question

what is positron ,antineutron?​

Answer 1

Answer:

it has the same mass as the neutron, and no net electric charge, but has opposite baryon number (+1 for neutron, −1 for the antineutron). ... In theory, a free antineutron should decay into an antiproton, a positron and a neutrino in a process analogous to thebeta decay of free neutrons.
