Hluav taws xob yog tseeb nyob deb deb ntawm lub nucleus ! Yog tias peb tuaj yeem nthuav dav qhov yooj yim hydrogen atom sotha nws nucleus (ib tug proton) yog qhov loj ntawm pob tawb, ces nws ib leeg hluav taws xob yuav nrhiav tau 2 mais deb.

Tsuas yog li ntawd, cov electrons puas yuav nyob ze rau lub nucleus?

Hluav taws xob nyob rau theem siab zog, uas nyob deb ntawm lub nucleus , muaj ntau zog. Lawv kuj muaj ntau orbitals thiab ntau dua tau tus lej ntawm electrons . Hluav taws xob ntawm lub zog sab nraud ntawm lub atom hu ua valence electrons . Lawv txiav txim siab ntau yam khoom ntawm ib lub caij.

Tsis tas li ntawd, pom dab tsi ntawm cov electrons thiab cov nucleus? Hluav taws xob yog pom nyob rau hauv lub plhaub los yog orbitalst uas nyob ib ncig ntawm lub nucleus ntawm ib qho atom. Protons thiab neutronsare pom hauv nucleus . Lawv ua ke ua ke nyob rau hauv nruab nrab ntawm lub atom.

Kuj paub, qhov kev ncua deb ntawm ib tug proton thiab electron yog dab tsi?

Cov hluav taws xob thiab proton ntawm hydrogen atomare sib cais (qhov nruab nrab) los ntawm a nyob deb 5,3 x 10-11 m.

Vim li cas electrons nyob sab nraum lub nucleus?

Tsis zoo li protons thiab neutrons, uas nyob rau hauv nucleus nyob rau hauv nruab nrab ntawm lub atom, electrons pom sab nraum lub nucleus . Vim hais tias opposite hluav taws xob tsub kom ib leeg, tsis zoo electrons yog attracted rau qhov zoo nucleus.
