Dalton yog ntau tus kws tshawb fawb. Democritus yog ib tug Greek philosopher, thiab yog li ntawd, yeej tsis thim ib lub tswv yim nrog kev sim. Democritus nug hais tias tej yam yuav ua tau infinitely loj los yog me me. Nws tau hais tias muaj kev txwv rau "me me", yog li tus atom , uas txhais tau tias nyob rau hauv Greek, "indivisible".

Ib yam li ib tug yuav nug, Dalton txoj kev xav txawv ntawm Democritus li cas?

Democritus thiab Dalton muaj cov tswv yim zoo sib xws txog lub atom, tab sis Democritus raws li nws kev xav ntau yog vim li cas tshaj science. Nws cov tswv yim zoo ib yam li cov Democrites uas nws ntseeg hais tias atoms yog indivisible thiab thatatoms ntawm ib yam khoom yog tag nrho cov zoo li tab sis yog. txawv los ntawm atoms ntawm lwm yam khoom.

Tsis tas li ntawd, Dalton lub atomic txoj kev xav yog dab tsi? ːlt?nz) chemistry. tus kev xav qhov teeb meem no muaj indivisible hais hu ua atoms thiab qhov ntawd atoms ntawm ib lub ntsiab yog txhua yam zoo tib yam thiab tsis tuaj yeem tsim los yog rhuav tshem. Cov tshuaj yog tsim los ntawm kev sib xyaw ua ke ntawm atoms nyob rau hauv yooj yim ratios muab compound atoms (molecules).

Tsis tas li ntawd, qhov twg ntawm Dalton's atomic txoj kev xav tsis raug?

Drawbacks ntawm Dalton's Atomic Theory Indivisibility ntawm ib atom tau ua pov thawj yuam kev :ib atom Nws tuaj yeem muab faib ua cov protons, neutrons thiab electrons. Txawm li cas los xij ib atom yog qhov tsawg tshaj plaws particle uas siv ib feem nyob rau hauv tshuaj tiv thaiv. Raws li Dalton , cov atoms ntawm tib lub ntsiab yog zoo ib yam nyob rau hauv tag nrho cov respects.

Vim li cas Dalton txoj kev xav tau txais?

Atoms yog indivisible. Thaum lub sij hawm tshuaj tiv thaiv, atomscan yuav tsum rearranged. Ib qho atom yog qhov tsawg tshaj plaws ntawm cov khoom. Dalton txoj kev xav ua dav txais vim nws tau ua raws li cov ntaub ntawv kev sim ntau, tsis yog kev soj ntsuam zoo.
