John Dalton FRS (/ˈd?ːlt?n/; 6 Cuaj hlis 1766 – 27 Lub Xya hli ntuj 1844) yog lus Askiv kws tshuaj , 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 txog xim dig muag, qee zaum hu ua Daltonism hauv nws txoj kev hwm.
Hauv qhov no, John Dalton qhov kev sim yog dab tsi?
Dalton qhov kev sim ntawm gases coj mus rau nws nrhiav pom tias tag nrho cov siab ntawm ib tug sib tov ntawm gases npaum li cas rau cov sum ntawm ib feem ntawm lub siab uas txhua tus neeg gas exerted thaum nyob rau tib qhov chaw. Nyob rau hauv 1803 no scientific txoj cai officially tuaj mus rau lub npe hu ua Dalton tus Txoj Cai Ntawm Ib Feem Siab.
John Dalton ua nws txoj haujlwm nyob qhov twg? Dalton (1766–1844) yug los rau hauv tsev neeg Quaker me me hauv Cumberland, England, thiab rau feem ntau ntawm nws lub neej pib hauv nws lub zos tsev kawm ntawv thaum muaj hnub nyoog 12-tau txais nws nyob ua ib tug xib fwb thiab pej xeem lecturer.
Tom qab ntawd, qhov twg ntawm Dalton txoj kev xav tsis raug?
Drawbacks ntawm Dalton tus Atomic Kev xav Lub indivisibility ntawm ib tug atom tau ua pov thawj yuam kev : ib qho atom tuaj yeem muab faib ua protons, neutrons thiab electrons. Txawm li cas los xij, ib qho atom yog qhov tsawg tshaj plaws uas siv ib feem hauv tshuaj tiv thaiv. Raws li Dalton , cov atoms ntawm tib lub ntsiab yog zoo sib xws nyob rau hauv tag nrho cov respects.
John Dalton tus qauv ntawm lub atom hu ua dab tsi?
Dalton's Model ntawm ib Atom Raws li tag nrho nws cov kev soj ntsuam, Dalton thov nws qauv ntawm ib atom . Nws feem ntau hu ua lub pob billiard qauv . Nws txhais ib atom los ua ib lub pob zoo li cov qauv, raws li lub tswv yim ntawm atomic nucleus thiab electrons tsis paub thaum lub sijhawm.
