Which type of radiation has a negligible mass and a charge of +1?

Question

Quizplus · Accepted Answer

Positrons are the antiparticles of electrons, having the same mass as an electron but with a positive charge. Unlike alpha particles, which have a significant mass and a +2 charge, and beta particles, which are electrons or positrons with a -1 or +1 charge respectively but are considered in this context to have a negligible mass, positrons fit the description of having a negligible mass and a charge of +1. Gamma rays are a form of electromagnetic radiation and do not have mass or charge.
