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.

Puas yog cov yeeb nkab diameters sab hauv lossis sab nraud?
In luv luv: Tube ntsuas los ntawm sab nraud txoj kab uas hla, pipe yog ntsuas los ntawm sab hauv txoj kab uas hlaMuaj feem ntau tsis meej pem txog qhov loj npaum li cas tus neeg yuav tsum tau xav tau - Pipe Size lossis Tubing Size. Nco ntsoov tias cov yeeb nkab loj yog hais txog qhov nominal - tsis tseeb - hauv txoj kab uas hla .
Lub plhaub sab nraud electrons li cas?
Tus naj npawb ntawm cov hluav taws xob nyob rau hauv lub plhaub sab nraud ntawm ib qho atom txiav txim siab nws reactivity, lossis nyiam tsim cov tshuaj sib txuas nrog lwm cov atoms. Lub plhaub sab nraud no hu ua lub plhaub valence, thiab cov hluav taws xob pom nyob hauv nws hu ua valence electrons .
Puas yog lub kaum sab xis ntawm qhov xwm txheej sib npaug ntawm lub kaum sab xis ntawm refraction?
Lub kaum sab xis ntawm qhov xwm txheej yog sib npaug rau lub kaum ntawm kev xav tsis cuam tshuam. … Thaum lub teeb hluav taws xob (piv txwv li, qhov teeb meem hluav taws xob) mus los ntawm qhov tsis tshua muaj mus rau qhov nruab nrab denser, lub teeb hluav taws xob (refracted ray) khoov mus rau qhov qub hauv qhov nruab nrab denser .
Puas muaj 4 electrons nyob hauv lub plhaub sab nraud?
Carbon (C), raws li pawg 14 lub caij, muaj plaub lub electrons hauv nws lub plhaub sab nrauv. Cov pa roj carbon feem ntau faib cov hluav taws xob kom ua tiav lub plhaub valence, tsim cov ntawv cog lus nrog ntau lwm cov atoms . Atom puas tuaj yeem poob 4 electrons?
Qhov txawv ntawm qhov kev thov sab hauv thiab sab nraud yog dab tsi?
Cov Tswv Yim Sab Hauv. Cov lus pom zoo yuav yog sab nraud lossis sab hauv. Ib qho tawm tswv yim sab nraud yog sau rau cov neeg tuaj saib sab nraud ntawm koj lub koom haum, thaum lub tswv yim sab hauv yog sau rau kev noj hauv koj lub koom haum .
