Discovery of Electron. Hauv 1830, Michael Faraday tau qhia tias yog hluav taws xob dhau los ntawm kev daws ntawm electrolyte, nws ua rau muaj tshuaj lom neeg ntawm electrodes. Cov tshuaj tiv thaiv ua rau liberation thiab deposition ntawm cov teeb meem ntawm cov electrodes. Cov txiaj ntsig no qhia txog qhov xwm txheej ntawm hluav taws xob.
Leej twg nrhiav tau lub electron?
Txawm tias J. J. Thomsontau lees paub nrog qhov kev tshawb pom ntawm cov hluav taws xob raws li nws qhov kev sim nrog cathode rays hauv xyoo 1897, ntau tus kws kho mob, suav nrog William Crookes, Arthur Schuster, Philipp Lenard, thiab lwm tus, uas tau ua kev sim cathode rays thov. tias lawv deserved credit.
Leej twg nrhiav tau electron Thomson los yog Faraday?
Lub sijhawm xyoo 1880 thiab 90s cov kws tshawb fawb tau tshawb nrhiav cathode rays rau cov cab kuj ntawm cov khoom hluav taws xob hauv cov teeb meem. Lawv txoj haujlwm tau ua tiav hauv qhov kev tshawb pom los ntawm Askiv tus kws kho mob J. J. Thomson ntawm cov hluav taws xob hauv xyoo 1897.
Faraday nrhiav tau dab tsi txog atoms?
Nyob rau xyoo 1830, Michael Faraday, tus kws tshawb fawb Askiv Askiv, tau ua ib qho kev tshawb pom tseem ceeb tshaj plaws uas ua rau lub tswv yim tias atoms muaj cov khoom siv hluav taws xob. Faraday tso ob lub electrodes nyob rau hauv ib qho kev daws ntawm cov dej uas muaj ib tug yaj compound.
Leej twg nrhiav tau proton ua ntej?
Tus proton tau tshawb pom los ntawm Ernest Rutherford nyob rau thaum ntxov 1900's. Nyob rau lub sijhawm no, nws txoj kev tshawb fawb tau ua rau muaj kev cuam tshuam nuclear uas ua rau thawj 'splitting' ntawm lub atom, qhov uas nws nrhiav tau protons. Nws hu nws qhov kev tshawb pom "protons" raws li Greek lo lus "protos" uas txhais tau tias ua ntej.
