Qhov chaw khoob nruab nrab lub atomic huab ntawm ib atom thiab nws nucleus tsuas yog hais tias: qhov chaw khoob, lossis lub tshuab nqus tsev. Hluav taws xob yog li 'hloov tawm' heev me ntsis hauv lawv cov orbits txog cov nucleus . Qhov tseeb, yoj-functions rau electrons hauv s-orbitals txog a nucleus ua tau txuas txhua txoj kev mus rau hauv lub nucleus nws tus kheej.

Tib neeg kuj nug, dab tsi nyob nruab nrab ntawm lub nucleus thiab cov electrons?

Electrons pom nyob rau hauv lub plhaub los yog orbitals uas nyob ib ncig ntawm lub nucleus ntawm ib qho atom. Protons thiab neutrons pom hauv nucleus . Lawv ua ke ua ke nyob rau hauv nruab nrab ntawm lub atom.

Tsis tas li ntawd Paub, dab tsi ua rau electrons los ntawm crashing rau hauv lub nucleus? Lub tswv yim, thawj zaug ua nyob rau hauv 1913, hais tias lub centrifugal quab yuam ntawm lub kiv puag ncig hluav taws xob tsuas yog raws nraim sib npaug lub zog txaus nyiam ntawm nucleus (nyob rau hauv kev sib piv nrog lub centrifugal quab yuam ntawm lub hli nyob rau hauv nws orbit raws nraim counteracting lub rub ntawm lub ntiaj teb lub ntiajteb txawj nqus) yog ib tug zoo duab, tab sis tsuas yog untenable.

Hauv qhov no, qhov chaw nyob ib puag ncig lub nucleus hu ua dab tsi?

Hloov chaw, nws tsuas yog ua tau los piav txog qhov muaj feem ntawm kev nrhiav ib qho hluav taws xob hauv ib cheeb tsam nyob ib ncig ntawm lub nucleus . Lub cheeb tsam uas ib tug electron feem ntau yuav yog hu ua ib orbital. Txhua lub orbital tuaj yeem muaj ntau tshaj ob lub electrons. A: Cov nucleus yog nyob nruab nrab ntawm txhua lub orbital.

Qhov chaw ntawm subatomic hais yog dab tsi?

Nws yog lub tshuab nqus tsev. Lub tshuab nqus tsev nruab nrab lub sub atomic cov khoom tuaj yeem muaj lwm yam me me pervasive elementary tsis sib tham sib cov khoom xws li neutrinos.
