Meaning and Definition
Another term for a positron, the antimatter counterpart of an ordinary electron, having the same mass but a positive electric charge.
In particle physics, an elementary particle with a positive charge equal in magnitude to the electron's negative charge. Its discovery confirmed the existence of antimatter predicted by Dirac's equation. Informally, sometimes used historically or in educational contexts to describe the concept.

FAQ
Frequently Asked Questions
No. A positron/positive electron is the antimatter counterpart of an electron, with the same small mass. A proton is a much heavier particle found in atomic nuclei.
'Positron' is the official, concise term coined by physicists. 'Positive electron' is descriptive but longer and can be confused with other positive particles in casual speech.
In cosmic rays, certain types of radioactive decay (beta-plus decay), and medical PET (Positron Emission Tomography) scans.
They undergo annihilation, a process where both particles are destroyed and their mass is converted into energy in the form of gamma rays.
Another term for a positron, the antimatter counterpart of an ordinary electron, having the same mass but a positive electric charge.
Positive electron is usually technical / scientific in register.
Positive electron: in British English it is pronounced /ˈpɒz.ə.tɪv ɪˈlek.trɒn/, and in American English it is pronounced /ˈpɑː.zə.t̬ɪv ɪˈlek.trɑːn/. Tap the audio buttons above to hear it.
