Atomic carbon muaj rau lub tshuab hluav taws xob: ob lub plhaub sab hauv (tub ntxhais) electrons hauv 1s orbital, thiab plaub valence (sab nraum lub plhaub) electrons hauv 2s thiab 2p orbitals.
Puas carbon muaj 4 lossis 8 valence electrons?
Kev piav qhia: Txoj cai octet hais tias atoms tuaj yeem sau lawv cov plhaub sab nraud nrog txog 8 electrons (lub plhaub tag nrho ntawm 8 yog qhov ruaj khov tshaj plaws). Txij li thaum Carbon tsuas muaj 4 ntawm nws cov khoom siv hluav taws xob sab nraud (los yog valence electrons) tag nrho, nws muaj chaw ua cov ntawv cog lus nrog 4 lwm cov atoms, piv txwv tias lawv yog ib daim ntawv cog lus.
Puas carbon muaj 2 lossis 4 valence electrons?
Piav: Cov pa roj carbon muaj rau lub tshuab hluav taws xob hauv nws lub xeev nruab nrab. Valance electrons yog cov electrons nyob rau sab nraud ntawm lub zog. Thawj ob lub electrons nkag mus rau hauv 1 s orbital lub zog qis tshaj plaws.
Tus nqi valence ntawm carbon yog dab tsi?
Carbon yog nyob rau hauv pawg 4A, yog li nws muaj 4 valence electrons.
Vim li cas cov pa roj carbon ntau yog 2?
Piv txwv li: Hauv $CO$ carbon muaj qhov tseem ceeb ntawm $2$. Qhov no yog vim carbon qhia nws ob lub electrons nrog oxygen thiab oxygen, tig nws ob lub electrons nrog carbon… txawm qhia nws cov electrons.
