Cov lus teb yog qhov hluav taws xob - huab qauv . Erwin Schrodinger's qauv , tsis zoo li lwm tus qauv , ua yeeb yam electrons raws li ib feem ntawm 'huab' qhov twg tag nrho electrons nyob hauv tib qhov chaw ib zaug.

Hais txog qhov no, tus qauv atomic twg hais tias nws tsis tuaj yeem paub qhov tseeb ntawm electrons?

Hauv Bohr qauv , ib electron cov txoj hauj lwm yog paub meej vim hais tias nws orbits lub nucleus nyob rau hauv ib tug taag txoj kev. Hauv hluav taws xob huab qauv , cov electron cov txoj haujlwm tsis tuaj yeem paub meej. Tsuas yog nws qhov tshwm sim qhov chaw tuaj yeem paub. Sib piv cov niaj hnub ( hluav taws xob huab) qauv ntawm atom nrog Dalton's atomic qauv.

Kuj Paub, yuav ua li cas tshwm sim thaum lub electron txav ntawm thawj lub zog mus rau qhov thib ob? Teb: Thaum twg electron txav los ntawm thawj lub zog mus rau theem ob lub zog , zog yog absorbed. Piav: Thaum ib electron txav los ntawm thawj lub zog mus rau theem ob lub zog , zog yog absorbed los ntawm lub atom uas txhais tau tias cov hluav taws xob dhia los ntawm qis qib zog mus siab dua qib zog.

Kuj paub, qhov sib npaug twg tau siv los ntawm Albert Einstein los piav qhia cov nyhuv photoelectric?

Ib feem tseem ceeb ntawm nws cov lus piav qhia yog qhov nws hais tias qhov no tuaj yeem suav nrog siv nws kev sib npaug ntawm lub zog sib npaug zaus sib npaug los ntawm Planck qhov tas li (6.62606876 * 10-34 J· os). Einstein ces piav qhov cov nyhuv photoelectric siv Planck cov lus piav qhia.

JJ Thomson tuaj yeem xaus li cas los ntawm nws qhov kev sim?

Raws li ib feem ntawm nws cov kev sim nrog cathode rays, Thomson sim hloov cov khoom siv cathode, uas yog lub hauv paus ntawm cov khoom. Txij li cov khoom qub tau tawm txawm tias cov khoom siv cathode hloov mus rau cov hlau sib txawv, Thomson xaus lus hais tias cov particle yog ib feem tseem ceeb ntawm tag nrho cov atoms.
