Ntxiv cov Hluav taws xob rau EveryFullOrbital
Ntxiv cov ntau kawg ntawm cov electrons uas txhua lub orbital tuaj yeem tuav. Sau qhov no tus lej rau tom qab siv. Forexample, thawj orbital yuav tuav ob electrons ob, yim; thiab qhov thib peb, 18. Yog li ntawd lub threeorbitalscombined tuaj yeem tuav 28 electrons.
Ib yam li ntawd ib tug yuav nug, koj yuav ua li cas thiaj nrhiav tau qhov siab tshaj plaws ntawm cov hluav taws xob hauv lub subshell?
Txhua subshell muaj ib Qhov siab tshaj plaws numberofelectrons uas nws muaj peev xwm tuav tau: s - 2 electrons ,,p -6 electrons , d-10 ib electrons , thiab f-14 electrons . Cov s subshell yog lub lowestenergy subshell thiab cov f subshell yog lub siab tshaj plaws subshell.
Dab tsi yog qhov siab tshaj plaws ntawm electrons hauv ib lub atom uas tuaj yeem muaj cov lej hauv qab no? Teb thiab piav qhia: Txhua lub orbital ua tau tuav ob electrons (18 ua tau).
Yog li ntawd, dab tsi yog qhov siab tshaj plaws ntawm electrons uas tuaj yeem cuam tshuam?
Txhua lub plhaub ua tau tsuas muaj ib tug ruaj numberoffelectrons : Thawj lub plhaub ua tau tuav ob electrons , lub plhaub thib ob ua tau tuav txog yim (2 + 6) electrons , lub plhaub thib peb ua tau tuav txog 18 (2 + 6 + 10) thiab lwm yam. General formula yog qhov nthshell ua tau hauv paus ntsiab lus tuav txog 2(n2) electrons.
Subshell yog dab tsi?
A subshell yog ib tug subdivision ntawm electronshells cais los ntawm electron orbitals. Subshells yog labelleds, p, d, thiab f nyob rau hauv ib tug electron configuration.
