Ua raws li qhov xav tau, muaj pes tsawg lub valence electrons nyob hauv 4th Plhaub?

Beryllim muaj 4 electrons --- 2 hauv thawj plhaub , thiab 2 hauv qhov thib ob plhaub (so ob cov valenceelectrons ). Boron muaj 5 electrons --- 2 hauv thawj plhaub , thiab 3 hauv ob plhaub (yog li peb cov valenceelectrons ). Carbon muaj 6 electrons --- 2 hauv thawj plhaub , thiab 4 hauv qhov thib ob plhaub (sofour valence electrons ).

Ib sab saum toj no, dab tsi yog qhov siab tshaj plaws ntawm electrons hauv 4th Plhaub? Yog li ntawd, lub thib plaub qib tuaj yeem tuav txog 32 electrons : 2 nyob rau hauv lub orbital, 6 nyob rau hauv lub peb p orbitals, 10 nyob rau hauv lub tsib d orbitals, thiab 14 nyob rau hauv lub xya f orbitals. Thesublevels ntawm thawj plaub lub tseem ceeb zog theem thiabthe ntau kawg ntawm cov electrons uas cov sublevels cancontainare summarized nyob rau hauv Table 5.1.

Ib yam li ntawd, pes tsawg electrons tuaj yeem tuav lub plhaub valence?

18

Vim li cas 3rd plhaub 8 lossis 18?

Qhov no yog vim nws yog lub siab tshaj plaws muaj peev xwm ntawm lub 3rd cev thiab nws tsis qhia txog qhov kev txiav txim uas theelectrons tau sau. Qhov 2, 8 , 18 , … Kev teeb tsa tau qhia txog qib 10 hauv cov tsev kawm ntawv. Cov lus teb rau koj cov lus nug yog nyob rau hauv kev paub muaj configuration ofelements.
