Lub Rutherford Kub Foil kev sim tua feeb hais ntawm ib daim ntawv nyias kub . Nws tau pom tias ib feem me me ntawm cov khoom tau deflected, thaum feem ntau dhau los ntawm daim ntawv. Qhov no ua rau Rutherford xaus lus tias qhov loj ntawm ib lub atom yog concentrated ntawm nws qhov chaw.

Yog li ntawd, qhov kev sim ntawm cov ntawv ci kub ua haujlwm li cas?

Lesson Summary Rutherford's kub foil sim qhia tau hais tias cov atoms feem ntau yog qhov chaw khoob, nrog rau cov nqi zoo concentrated hauv lub nucleus. Nws paub qhov no vim hais tias feem ntau ntawm cov alpha hais tau ncaj qha los ntawm daim ntawv ci , tsuas yog ob peb deflected ntawm cov ces kaum loj.

Kuj Paub, vim li cas Rutherford cov tub ntxhais kawm xav tsis thoob los ntawm cov txiaj ntsig ntawm kev sim cov ntawv nyiaj kub? Rutherford nrhiav pom cov proton, thiab nws kuj pom tias lub atom yog qhov chaw khoob. Nws pom tias ib tug beam ntawm alpha hais yog tawg ri niab rov qab qhov twg nws tuaj los ntawm kub atoms, thiab, txij li nws yog paub tias alpha hais tau positive, nws yog deduced tias muaj yog ib tug ntom zoo core nyob rau hauv lub nucleus.

Yog li ntawd, dab tsi yog qhov xav tau ntawm cov ntawv ci kub sim?

Cov xav tau ntawm kev sim yog tias tag nrho cov alpha hais yuav dhau los ntawm ntawv ci yam tsawg kawg deflection. Cov no tshwm sim muab lub tswv yim tias lub atom muaj feem ntau ntawm qhov chaw khoob thiab feem ntau ntawm cov huab hwm coj thiab zoo ntawm lub atom yog nyob rau hauv ib tug me me core hu ua lub nucleus.

Vim li cas nws thiaj li hu ua cov ntawv xov xwm kub?

Vim nws yog lub npe ntawm lub kev sim Rutherford tau nrhiav cov qauv atomic tshiab. Nws siv nyias ntawv ci thiab foob nws nrog alpha hais. Vim nws yog lub npe ntawm lub kev sim Rutherford tau nrhiav cov qauv atomic tshiab. Nws siv nyias ntawv ci thiab foob nws nrog alpha hais.
