Lub Kaum Hli 1897: Kev Tshawb Fawb ntawm Electron.
Puas yog cov proton lossis electron pom thawj zaug?
thawj subatomic particle rau raug txheeb xyuas yog cov hluav taws xob, xyoo 1898. Kaum xyoo tom qab, Ernest Rutherford pom tias atoms muaj cov nucleus ntom ntom, uas muaj cov protons. Xyoo 1932, James Chadwick nrhiav tau lub neutron, lwm qhov chaw nyob hauv lub nucleus.
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.
Leej twg yog thawj tus kws tshawb fawb los tshawb pom electrons?
Joseph John “J. J. Thomson. Xyoo 1897 Thomson nrhiav pom lub tshuab hluav taws xob thiab tom qab ntawd mus rau kev tawm tswv yim rau cov qauv ntawm lub atom. Nws txoj hauj lwm kuj tau coj mus rau qhov kev tsim ntawm qhov loj spectrograph.
Leej twg nrhiav tau electrons hauv xyoo 1897?
Thomson tshaj tawm txoj kev tshawb pom ntawm electrons. Lub Plaub Hlis 30, 1897, British physicist J. J. Thomson tshaj tawm nws qhov kev tshawb pom tias atoms tau tsim los ntawm cov khoom me me.
