Joseph John Thomson (J. J. Thomson, 1856-1940; saib daim duab ntawm American Institute of Physics) tau lees paub dav dav tias yog tus neeg nrhiav pom hluav taws xob.

Leej twg hu ua electron?

(Lub sij hawm "electron" yog coined nyob rau hauv 1891 los ntawm G. Johnstone Stoney los qhia txog chav tsev ntawm tus nqi pom hauv kev sim uas dhau hluav taws xob los ntawm cov tshuaj; nws yog Irish physicist George Francis Fitzgerald uas tau tawm tswv yim hauv xyoo 1897 tias lo lus raug siv rau Thomson lub cev nqaij daim tawv.)

JJ Thomson nrhiav tau electrons li cas?

J. J. Thomson qhov kev sim nrog cov kab hluav taws xob cathode tau pom tias tias txhua lub atoms muaj me me tsis zoo them subatomic hais lossis electrons. Thomson's plum pudding qauv ntawm lub atom muaj qhov tsis zoo-them electrons embedded nyob rau hauv ib tug zoo-them "kua zaub."

Leej twg nrhiav tau hluav taws xob hauv Is Nrias teb?

J. J. Thomson hauv xyoo 1897. Hauv kev sim nrog Crookes, lossis cathode ray, raj, nrhiav pom cov hluav taws xob. Nws pom tias cov kab hluav taws xob cathode raug them tsis zoo.

Electron thawj hu ua dab tsi?

Lub sijhawm xyoo 1800 nws tau pom tseeb tias cov nqi hluav taws xob muaj lub ntuj tsim, uas tsis tuaj yeem faib ua lwm yam ntxiv, thiab xyoo 1891 Johnstone Stoney tau thov kom nws lub npe "electron." Thaum J. J. Thomson nrhiav pom lub teeb particle uas nqa qhov nqi ntawd, lub npe "electron" tau siv rau nws.
