Nyob ntawd yog plaub ua tau ua ke rau nqes l thiab m l rau = 2 . Cov = 2 Lub zog tseem ceeb muaj xws li lub orbital thiab p orbital.

Kuj tseem paub yog, muaj pes tsawg qhov sib xyaw ua ke muaj rau qhov txiaj ntsig ntawm L thiab ML thaum n 5?

Teb thiab piav qhia: Thaum twg = 5 l ib tuaj yeem yog 0, 1, lossis 2. Cov no tus nqi sib raug rau s, p, d thiab f orbitals. Cov m l nqi Qhov ntau ntawm -3 txog +3.

Ib yam li ntawd, dab tsi yog qhov txiaj ntsig ntawm L rau lub orbital no? Piv txwv li, rau ib qho s orbital , l = 0, thiab tus nqi ntawm m l yog zero. Rau p orbitals, l = 1, m l tuaj yeem muab sib npaug rau -1, 0, lossis +1. Feem ntau hais lus, m l tuaj yeem sib npaug rau - l , –( l – 1), …, –1, 0, +1, …, ( l – 1), l . Tag nrho cov naj npawb ntawm ua tau orbitals nrog tib tus nqi ntawm l (ib subshell) yog 2l + 1.

Yog li, dab tsi yog qhov ua tau ntawm L rau txhua tus nqi ntawm n?

vim = 3 tau tus nqi ntawm l = 0, 1, 2, uas qhia cov duab ntawm txhua subshell.

  • Thawj lub plhaub nrog n = 1 muaj ib qho subshell (l = 0)
  • Lub plhaub tseem ceeb nrog n = 2 muaj ib qho s subshell thiab ib p subshell (l = 0, 1)
  • Lub plhaub tseem ceeb nrog n = 3 muaj ib lub subshell, ib tug p subshell, thiab ib tug d subshell (l = 0, 1, 2)

Thaum N 4 Qhov ua tau ntawm L yog dab tsi?

Teb thiab piav qhia: Rau n = 4 , cov tau tus nqi ntawm l yog 0, 1, 2, thiab 3. Yog l = 0, ua ua tau m_l yog 0.
