Daim duab 01: Democritus

Peb tsis tuaj yeem tsim lawv, thiab qhov sib xyaw ntawm atoms hauv cov khoom txiav txim siab qhov zoo ntawm cov khoom ntawd. Txawm li cas los xij, qhov kev xav no tau ua kom zoo dua qub thiab nthuav dav tom qab los ntawm Greek philosopher Epicurus (341 - 270 BC).

D alton Atomic Theory yog dab tsi?

D alton atomic theory yog ib txoj kev tshawb fawb niaj hnub no uas piav txog qhov xwm txheej ntawm cov atoms. Nrog rau txoj kev loj hlob ntawm txoj cai ntawm kev txuag ntawm huab hwm coj thiab txoj cai ntawm cov proportions meej, John D alton tsim ib lub tswv yim tshiab raws li txoj cai ntawm ntau proportions. Nws hais tias yog tias tib ob lub ntsiab lus tuaj yeem sib xyaw ua ke los tsim ntau lub tebchaw sib txawv, ces qhov sib piv ntawm qhov loj ntawm ob lub ntsiab lus hauv lawv cov tebchaw sib txawv yuav raug sawv cev los ntawm cov lej me me.

Tom qab ntawd, nws tau tsim D alton atomic txoj kev xav uas muaj cov lus hauv qab no.

  1. Txhua yam tshuaj muaj cov khoom me me uas tsis pom qhov muag liab qab; atoms.
  2. Peb tsis tuaj yeem tsim lossis rhuav tshem atoms.
  3. Tag nrho cov atoms ntawm tib cov tshuaj muaj pes tsawg leeg yog sib npaug hauv pawg thiab lwm yam khoom.
  4. Thaum tsim cov khoom sib xyaw, cov ntsiab lus sib txawv ua ke sib txawv tab sis cov lej yooj yim.

Daim duab 02: Txoj Cai Kev Tiv Thaiv Pawg piav qhia tias Tag Nrho Cov Txheej Txheem hauv Tshuaj Ruaj Ntseg tseem nyob tas li.

Txawm li cas los xij, qhov kev xav ntawm atomic no tsis raug rau txhua qhov xwm txheej. Piv txwv li, nqe lus thib ob tsis raug vim tias peb tuaj yeem faib cov atom rau hauv subatomic hais ntawm nuclear fission. Qhov thib peb nqe lus yuav tsis raug vim muaj isotopes; atoms ntawm tib yam tshuaj uas sib txawv ntawm ib leeg raws li atomic masses. Txawm li cas los xij, peb tsis tuaj yeem siv cov ntsiab lus tsis raug no kom tshem tawm qhov kev xav no tag nrho vim tias nws tuaj yeem piav qhia txoj cai ntawm kev txuag ntawm huab hwm coj thiab kev cai lij choj ntawm qhov muaj pes tsawg leeg; Yog hais tias tag nrho cov atoms ntawm ib lub caij yog zoo ib yam nyob rau hauv loj thiab yog hais tias atoms sib sau ua ke nyob rau hauv tas li cov zauv ratios, cov feem pua ntawm cov compound yuav tsum muaj ib tug tshwj xeeb tus nqi yam tsis hais txog cov qauv soj ntsuam.
