Rutherford's Gold Foil Experiment Ua pov thawj qhov muaj nyob ntawm qhov chaw me me loj rau atoms, uas tom qab ntawd yuav raug hu ua lub nucleus ntawm atom. Ernest Rutherford , Hans Geiger thiab Ernest Marsden nqa tawm lawv Kub Foil Experiment los soj ntsuam cov nyhuv ntawm alpha hais txog qhov teeb meem.

Ib yam li ntawd, Rutherford sim ua dab tsi thiab nws nrhiav tau dab tsi?

Rutherford overturned Thomson tus qauv xyoo 1911 nrog nws cov neeg paub zoo kub foil sim hauv qhov twg nws qhia tau hais tias lub atom muaj ib tug me me thiab hnyav nucleus. Rutherford tsim ib kev sim siv cov alpha hais tawm los ntawm cov khoom siv hluav taws xob raws li kev sojntsuam mus rau lub ntiaj teb tsis pom ntawm cov qauv atomic.

Qhov thib ob, peb qhov kev soj ntsuam tseem ceeb yog dab tsi Rutherford tau ua hauv kev sim cov ntawv ci kub? 1) Feem ntau ntawm Alpha hais dhau ncaj qha los ntawm ntawv ci tsis muaj deflection los ntawm lawv txoj kev qub. 2) Ob peb Alpha hais yog deflected los ntawm lub kaum sab xis me me thiab ob peb yog deflected los ntawm lub kaum sab xis loj.

Tsuas yog li ntawd, Rutherford qhov kev sim ua cov ntawv nyiaj kub ua haujlwm li cas?

Rutherford's gold foil thwmsim (thiab lwm yam hlau foil kev sim ) koom nrog firing zoo them alpha hais ntawm ib daim kub / hlau ntawv ci . Yuav kom cov alpha hais kom deflected, lawv yuav tsum tau ntaus los yog los ze rau ib tug zoo nqi particle nyob rau hauv lub atom.

Rutherford txoj kev sim hu ua dab tsi?

Lub Geiger-Marsden kev sim (kuj hu ua Rutherford kub ntawv nyiaj kev sim ) yog ib tug series ntawm landmark kev sim los ntawm qhov uas cov kws tshawb fawb pom tias txhua lub atom muaj cov nucleus uas nws cov nqi zoo thiab feem ntau ntawm nws cov huab hwm coj yog concentrated.
