Description : The antiparticle of an electron is – (1) Positron (2) Proton (3) Alpha particles (4) Beta particles
Last Answer : (1) Positron Explanation: Corresponding to most kings of particles, there is an associated antiparticle with the same mass and opposite charge (including electric charge). The antiparticle of the ... radioactive decay. The opposite is also true: the antiparticle of the positron is the electron.
