Teb: Kev Xaiv D) Ob tus qauv vim tias txhua tus qhia tau hais tias muaj hluav taws xob nyob hauv lub plhaub sab nraud. Kev piav qhia: Nws pom meej meej tias qauv 1 thiab qauv 2 muaj cov khoom siv hluav taws xob uas zoo ib yam rau cov poov tshuaj. Lub reactivity nyob rau hauv poov tshuaj yog pom vim hais tias ntawm ib tug electron tam sim no nyob rau hauv lub outermost valence plhaub.
Tus qauv twg yog qhov muaj txiaj ntsig zoo hauv kev qhia txog kev rov ua haujlwm ntawm cov poov tshuaj Tsis yog tus qauv tsis tuaj yeem qhia qhov tshwm sim ntawm cov poov tshuaj Model 1 vim nws pom cov hluav taws xob hauv 4s orbital qauv 2 vim nws pom cov hluav taws xob nyob hauv lub nplhaib sab nraud?
Tsis yog tus qauv tsis muaj peev xwm qhia tau cov tshuaj poov tshuaj. Model 1 vim nws pom ib qho hluav taws xob hauv 4s orbital. Qauv 2 vim nws qhia tau hais tias ib qho hluav taws xob nyob rau hauv lub nplhaib sab nraud. Ob leeg qauv vim hais tias txhua tus qhia ib qho hluav taws xob nyob rau hauv lub plhaub sab nraud.
Qhov twg yog qhov kev teeb tsa hluav taws xob rau zinc quizlet?
Zinc's full electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 3d10.
Koj ua li cas Li+?
Qhov no txhais tau hais tias qhov nruab nrab lithium atom yuav muaj tag nrho 3 electrons nyob ib puag ncig nws cov nucleus. Tam sim no, lithium cation, Li +, yog tsim thaum lithium poob lub electron nyob rau ntawm nws lub plhaub sab nraud → nws cov valence electron. Cov hluav taws xob no nyob ntawm qib thib ob lub zog, hauv 2s-orbital.
Muaj pes tsawg 3d electrons nyob hauv CR?
Ib atom Crmuaj ib tug 4s electron thiab tsib 3d electrons.
