See it in a sentence
Early twentieth-century physicists used "negatron" to make clear they meant the ordinary, negatively charged electron rather than its antimatter counterpart.
The term negatron largely fell out of use once "electron" alone became understood to mean the negative particle by default.
A note on using this word
Physicist Arthur Compton is credited with popularizing "negatron" in the 1930s specifically to contrast with the newly discovered positron.
