Hauv qhov no, muaj pes tsawg tus electrons tuaj yeem tuav 4th Plhaub?
Cov qib plaub lub zog muaj 18 electrons . Cov qib plaub lub zog ntawm lub rooj zaum muaj xws li 4s 3d thiab 4p orbitals. Lub 4p orbital tuav 6 electrons.
Ib sab saum toj no, pes tsawg tus electrons tuaj yeem nyob tag nrho ntawm N 4 orbitals? Lub sublevel tsuas muaj ib qho orbital, yog li tuaj yeem muaj 2 electrons max. P sublevel muaj 3 orbitals, yog li muaj peev xwm muaj 6 electrons max. d sublevel muaj 5 orbitals, yog li muaj peev xwm muaj 10 electrons max. Thiab 4 sublevel muaj 7 orbitals, yog li tuaj yeem muaj 14 electrons max.
Ib yam li ntawd, pes tsawg tus electrons tuaj yeem tuav tau n Plhaub?
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 ob tug electrons , lub plhaub thib ob tuaj yeem tuav tau txog yim (2 + 6) electrons, lub plhaub thib peb tuaj yeem tuav tau 18 (2 + 6 + 10) thiab lwm yam. Cov qauv dav dav yog tias lub plhaub nth tuaj yeem tuav txog 2 (n2) electrons.
Muaj pes tsawg electrons tuaj yeem nyob hauv N3 plhaub?
s-orbitals tuaj yeem tuav 2 electrons , p-orbitals tuaj yeem tuav 6 electron . Yog li, lub plhaub thib ob tuaj yeem muaj 8 electron . N = 3 (thib peb) plhaub muaj: Lub 3s orbital.
