Tus naj npawb ntawm cov hluav taws xob hauv lub plhaub sab nraud ntawm ib qho atom txiav txim siab nws cov reactivity, los yog nyiam tsim cov tshuaj bonds nrog lwm cov atoms. Lub plhaub sab nraud no hu ua valence plhaub, thiab cov hluav taws xob pom nyob hauv nws hu ua valence electrons.
Dab tsi yog electrons tsis nyob hauv lub plhaub sab nraud hu ua?
puab lub plhaub electrons yog cov electrons tsis nyob hauv lub plhaub sab nraud. Lawv tiv thaiv valence electrons los ntawm lub nucleus, txo cov nqi hluav taws xob zoo.
Puas yog cov electrons nyob hauv lub plhaub sab nraud?
Valence electrons yog cov electrons uas nyob hauv lub plhaub sab nraud uas nyob ib puag ncig lub atomic nucleus.
Muaj pes tsawg lub atom muaj pes tsawg electrons hauv nws lub plhaub sab nrauv?
Qhov no yog lub npe hu ua txoj cai octet, uas hais tias, tshwj tsis yog lub plhaub sab hauv, uas atoms ruaj khov dua thaum lawv muaj yim electrons hauv lawv lub plhaub valence, lub plhaub sab nraud ntawm electron.
Puas yog valence electrons nyob rau hauv lub plhaub sab nraud ntawm lub atom?
Valence electrons yog cov electrons nyob rau hauv outtermost plhaub, lossis qib zog, ntawm ib lub atom.
