Thawj Quantum Number: Orbital thiab Electron Calculations
Muaj n2 orbitals rau txhua tus qib zog . Rau n = 1, muaj 12 los yog ib orbital . Rau n = 2, muaj 22 los yog plaub orbitals . Rau n = 3 muaj cuaj orbitals rau n = 4, 16 orbitals rau n = 5, 52 = 25 orbitals , thiab lwm yam.
Tom qab ntawd, dab tsi yog lub orbital tam sim no nyob rau hauv lub thib tsib lub ntsiab lub zog?
Cov qib tsib lub zog tseem ceeb muaj s,p,d,f orbitals yog li lo lus teb yog tsab ntawv d.
Tom qab ntawd, lo lus nug yog, dab tsi yog lub zog tseem ceeb? Hauv chemistry, cov theem pib zog ntawm ib tug electron hais txog lub plhaub los yog orbital nyob rau hauv uas lub electron nyob rau hauv lub atom lub nucleus. Qhov no qib yog denoted los ntawm tus thawj coj quantum num n. Thawj lub caij nyob rau hauv ib lub sij hawm ntawm lub sij hawm lub sij hawm qhia ib tug tshiab theem pib zog.
Ua raws li qhov no hauv kev xav, pes tsawg lub orbitals nyob rau hauv txhua qib zog?
Txhua tus thawj coj qib zog saum tus thawj muaj ib s orbital thiab 3 p orbitals . Ib txheej peb p orbitals , hu ua p sublevel, muaj peev xwm tuav tau ntau tshaj ntawm rau electrons. Yog li ntawd, qhov thib ob qib tuaj yeem muaj qhov siab tshaj plaws ntawm yim electrons - uas yog, ob hauv s orbital thiab 6 hauv 3 p orbitals.
Muaj pes tsawg Subshells muaj nyob rau hauv lub zog tseem ceeb n 5?
Rau = 5 , qhov ua tau qhov tseem ceeb ntawm l = 0, 1, 2, 3, 4. Cov lej no suav nrog s, p, d, f thiab g orbitals . Tam sim no, s muaj 1 subshell ,p 3,d yog 5 , f muaj 7 thiab g muaj 9. Yog li, tag nrho cov naj npawb ntawm subshells = 25.

Muaj pes tsawg sublevels nyob rau hauv cov theem hauv qab no lub zog tseem ceeb?
Qib ib muaj ib tug sublevel – ib s. Qib 2 muaj 2 sublevels - s thiab p. Qib 3 muaj 3 sublevels - s, p, thiab d. Qib 4 muaj 4 sublevels - s, p, d, thiab f
Muaj pes tsawg lub orbitals nyob rau hauv lub plhaub N 4?
L=3 rau f subshell. Tus naj npawb ntawm orbitals yog = 2l + 1 = 7. Nws tuaj yeem ua rau tag nrho 14 electron. Li no rau lub plhaub ntawm tus thawj quantum tooj n = 4 muaj 16 orbitals, 4 subshells, 32 electrons (siab tshaj) thiab 14 electrons nrog l = 3
Muaj pes tsawg lub orbitals muaj nyob hauv M plhaub?
Lub plhaub M tsuas tuav yim electrons. Lub plhaub M tuaj yeem tuav txog 18 electrons thaum koj txav mus rau ntau dua atomic tooj. Qhov siab tshaj plaws ntawm cov hluav taws xob koj yuav pom hauv ib lub plhaub yog 32
Muaj pes tsawg electrons nyob hauv qib zog?
Txhua lub plhaub muaj peev xwm tsuas muaj tus naj npawb ruaj khov ntawm cov hluav taws xob: Thawj lub plhaub tuaj yeem tuav tau txog li ob lub tshuab hluav taws xob, lub plhaub thib ob tuaj yeem tuav tau txog yim (2 + 6) electrons, lub plhaub thib peb tuaj yeem tuav tau txog 18 (2 + 6 + 10). ) thiab lwm yam. Cov qauv dav dav yog tias lub plhaub nth tuaj yeem tuav txog 2 (n2) electrons
Koj puas paub tias muaj pes tsawg lub orbitals nyob hauv lub plhaub?
Tus naj npawb ntawm orbitals nyob rau hauv ib lub plhaub yog cov square ntawm tus thawj quantum tooj: 12 = 1,22 = 4, 32 = 9. Muaj ib tug orbitalin ib tug subshell (l = 0), peb orbitals nyob rau hauv ap subshell (l = 1) , thiab tsib orbitals hauv ad subshell (l = 2). Yog li ntawd, tus naj npawb ntawm orbitals hauv subshell yog 2(l) +1
