Ib yam li ntawd, Rutherford scattering sim yog dab tsi?

Rutherford's alpha particle scattering xyaum sim hloov txoj kev peb xav txog atoms. Rutherford qhia cov kab teeb ntawm alpha hais (uas yog lub nuclei ntawm helium atoms thiab li no zoo them) ntawm nyias cov ntawv ci kub los kuaj cov qauv no thiab sau tseg tias alpha hais li cas tawg tawg los ntawm foil.

Tsis tas li ntawd, vim li cas thiaj li Ernest Rutherford ua cov ntawv nyiaj kub? 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 tau ua tiav lawv Kub Foil Experiment los soj ntsuam cov nyhuv ntawm alpha hais txog qhov teeb meem.

Ib yam li ntawd, thaum twg Rutherford ua cov ntawv nyiaj kub?

1908 thiab 1913

Qhov txiaj ntsig ntawm Rutherford sim ua li cas?

Thomson's plum pudding qauv ntawm lub atom muaj qhov tsis zoo-them electrons embedded nyob rau hauv ib tug zoo-them "kua zaub." Rutherford's gold foil xyaum sim qhia tau hais tias lub atom feem ntau yog qhov chaw khoob nrog me me, ntom, zoo-them nucleus. Raws li cov no tshwm sim , Rutherford tau npaj cov qauv nuclear ntawm lub atom.
