Definition
Meaning and Definition
The elementary particle that is the antiparticle of the electron, possessing the same mass but opposite electric charge and quantum numbers.
Commonly known as a 'positron'. It annihilates with an electron upon contact, producing gamma-ray photons. The existence of antielectrons confirmed the theoretical prediction of antimatter.
Dialectal Variation
British vs American Usage
Differences
No significant difference in usage; both varieties use 'antielectron' in highly technical contexts, with 'positron' being the preferred term in both.
Connotations
Purely technical, with no regional connotative differences.
Frequency
Extremely low frequency in general language. 'Positron' is far more frequent in both British and American English scientific publications.

FAQ
Frequently Asked Questions
Yes, 'antielectron' and 'positron' refer to the exact same particle. 'Positron' is the more commonly used term.
Antielectrons are produced naturally in certain types of radioactive decay (beta-plus decay), in cosmic rays, and in particle accelerators. They are also used medically in Positron Emission Tomography (PET) scans.
They annihilate each other. Their combined mass is converted into energy, typically in the form of two gamma-ray photons moving in opposite directions.
'Positron' (coined from 'positive electron') is shorter, was adopted early in particle physics, and is the standard term in many applied fields like medical imaging. 'Antielectron' is a more systematic, descriptive term used in foundational physics contexts.
The elementary particle that is the antiparticle of the electron, possessing the same mass but opposite electric charge and quantum numbers.
Antielectron is usually technical/scientific in register.
Antielectron: in British English it is pronounced /ˌæn.ti.ɪˈlek.trɒn/, and in American English it is pronounced /ˌæn.taɪ.ɪˈlek.trɑːn/ or /ˌæn.t̬i.ɪˈlek.trɑːn/. Tap the audio buttons above to hear it.
