Ib yam li ntawd, John Dalton nrhiav tau atomic txoj kev xav li cas?
Dalton's atomic txoj kev xav tau hais tias txhua yam teeb meem yog tsim los ntawm atoms , indivisible thiab indestructible tsev blocks. Thaum tag nrho atoms ntawm ib lub ntsiab yog zoo tib yam, txawv cov ntsiab lus muaj atoms ntawm txawv qhov loj thiab loj.
Ib sab saum toj no, John Dalton nrhiav tau dab tsi? Qhov kev tshawb pom no coj mus rau ib qho ntawm nws qhov kev tshawb pom loj tshaj plaws: txhua qhov teeb meem yog tsim los ntawm ib tus neeg hu ua atoms. Nws tsim qhov kev tshawb pom no rau hauv nws atomic txoj kev xav . Dalton tau txais ntau yam kev qhuas rau txoj haujlwm nws tau ua.
Tsis tas li ntawd, John Dalton ua nws qhov kev tshawb pom qhov twg?
Atomic Theory Hauv ib tsab xov xwm nws tau sau rau Manchester Literary thiab Philosophical Society hauv 1803, Dalton tsim thawj daim duab ntawm atomic luj. Nrhiav kom nthuav dav nws txoj kev xav, nws nyeem cov ntsiab lus ntawm qhov hnyav atomic hauv nws phau ntawv A New System of Chemical Philosophy, luam tawm 1808.

Qhov kev tshawb pom ntawm John Dalton yog dab tsi?
John Dalton FRS (/ˈd?ːlt?n/; 6 Cuaj hlis 1766 – 27 Lub Xya hli ntuj 1844) yog ib tug Askiv chemist, physicist, thiab meteorologist. Nws paub zoo tshaj plaws rau kev qhia txog atomic txoj kev xav rau hauv chemistry, thiab rau nws txoj kev tshawb fawb rau hauv qhov muag tsis pom xim, qee zaum hu ua Daltonism hauv nws txoj kev hwm
Qhov kev tshawb xav loj loj tau tshawb pom li cas?
Cosmic microwave keeb kwm yav dhau hluav taws xob Nyob rau hauv 1964, Arno Penzias thiab Robert Wilson serendipitously pom lub cosmic keeb kwm yav dhau hluav taws xob, ib tug omnidirectional teeb liab nyob rau hauv lub microwave band. Lawv qhov kev tshawb pom tau muab kev pom zoo ntawm qhov kev twv loj loj los ntawm Alpher, Herman thiab Gamow nyob ib puag ncig xyoo 1950
Ernest Rutherford ua nws qhov kev tshawb pom qhov twg?
Rutherford ntawm Manchester, 1907–1919. Ernest Rutherford nrhiav tau lub nucleus ntawm lub atom hauv xyoo 1911
Dab tsi yog chromosome txoj kev xav ntawm kev qub txeeg qub teg thiab nws cuam tshuam li cas rau Mendel qhov kev tshawb pom?
Piav Mendel cov lus xaus txog qhov zoo li cas dhau ntawm ib tiam dhau ib tiam. Lub chromosome txoj kev xav ntawm kev qub txeeg qub teg hais tias cov yam ntxwv qub txeeg qub teg yog tswj los ntawm cov noob nyob rau ntawm chromosomes ncaj ncees kis los ntawm gametes, tswj cov caj ces txuas ntxiv ntawm tiam mus rau ib tiam
Dalton txoj kev xav tau ua li cas rau kev tshawb pom ntawm lwm cov ntsiab lus?
Thaum tag nrho cov atoms ntawm ib lub caij yog zoo tib yam, cov ntsiab lus sib txawv muaj atoms ntawm qhov sib txawv loj thiab loj. Dalton's atomic txoj kev xav kuj tau hais tias tag nrho cov tebchaw tau tsim los ntawm kev sib txuas ntawm cov atoms hauv qhov piv txwv. Dalton kuj tau tshaj tawm tias cov tshuaj lom neeg ua rau muaj kev hloov pauv ntawm cov atom reacting
