A particle of light energy is called a:

Explanation:
Light energy is carried in indivisible units called photons. A photon is the fundamental quantum of electromagnetic radiation, with energy proportional to its frequency (E = hf) and traveling at the speed of light, while having no rest mass. The other terms refer to different things: a positron is the antimatter partner of the electron, a neutron is a nucleon in the nucleus, and a betatron is a device used to accelerate particles. So the particle of light energy is a photon.
