Teb: N plhaub tuaj yeem muaj siab tshaj ntawm 32 electrons.
Puas muaj pes tsawg electrons nyob rau hauv lub plhaub kawg ntawm n?
Yog li … rau lub caij ntawm NITROGEN, koj twb paub lawm tias tus lej atomic qhia koj cov lej ntawm electrons. Qhov ntawd txhais tau tias muaj 7 electrons nyob rau hauv ib tug nitrogen atom. Saib ntawm daim duab, koj tuaj yeem pom muaj ob lub tshuab hluav taws xob hauv lub plhaub ib thiab tsib hauv plhaub ob.
KLMN plhaub yog dab tsi?
K txhais tau hais tias thawj lub plhaub (lossis qib zog), L lub plhaub thib ob, M, lub plhaub thib peb, thiab lwm yam. Hauv lwm lo lus, KLMN (OP) cov ntawv sau tsuas yog qhia tus naj npawb ntawm cov hluav taws xob ib qho atom muaj nrog txhua tus lej quantum (n)Daim ntawv SPDF subdivides txhua lub plhaub rau hauv nws cov subshells.
Dab tsi yog qhov txiaj ntsig ntawm KLMN plhaub?
Hauv kev teeb tsa hluav taws xob cov txiaj ntsig ntawm K L thiab M plhaub yog 2 8 thiab 16 raws liKev teeb tsa hluav taws xob yog kev faib tawm ntawm cov hluav taws xob ntawm lub atom lossis molecule hauv atomic lossis molecular orbitals. Piv txwv li, kev teeb tsa hluav taws xob ntawm Ca atom yog 1s2 2s2 2p6 3s2 3p6 4s2.
Vim li cas lub plhaub hu ua KLMN?
Cov zog no tau raug hu ua hom A uas muaj zog dua X-ray thiab hom B uas qis zog X-ray. Tom qab ntawd cov enegiers tau muaj npe nrog cov tsiaj ntawv sib txawv. Nws pom tias K hom X-rays tawm lub zog siab tshaj plaws Yog li ntawd, nws tau hu lub plhaub sab hauv tshaj li K plhaub.
