Ib lub zog tag nrho sab nraud yog qhov ruaj khov tshaj plaws ntawm cov hluav taws xob. Raws li qhov tshwm sim, cov pa roj carbon monoxide tsis tuaj yeem ua kom ruaj khov dua los ntawm kev cuam tshuam nrog lwm cov ntsiab lus thiab tau txais lossis poob valence electrons. Yog li ntawd, cov pa roj carbon monoxide tsis tshua muaj kev cuam tshuam hauv tshuaj lom neeg thiab yuav luag tsis tsim cov tshuaj sib xyaw nrog lwm cov ntsiab lus.
Puas muaj lub plhaub sab nraud tag nrho?
Pab pawg 18 cov ntsiab lus (helium, neon, thiab argon tau qhia) muaj tag nrho sab nrauv, lossis valence, plhaub. Lub plhaub valence tag nrho yogruaj khov hluav taws xob teeb tsa. … Lawv qhov tsis muaj qhov cuam tshuam tau ua rau lawv raug hu ua cov pa roj tsis zoo (lossis cov pa tsis zoo).
Tsev neeg twg muaj lub zog sab nraud?
Kev piav qhia: Cov pab pawg (tsev neeg) nrog cov ntsiab lus uas muaj tag nrho cov plhaub sab nraud yog cov pawg sab xis tshaj plaws ntawm lub rooj: cov roj av zoo: helium, neon, argon, krypton, xenon, thiab radon (cov ntsiab lus 118, oganesson, kuj yog nyob rau hauv pab pawg no, tab sis feem ntau ntawm nws cov tshuaj thiab lub cev muaj zog yog tseem tsis tau paub.
Thaum lub zog sab nraud puv puv?
Lub zog sab nraud ntawm feem ntau atoms yuav ua tiav thaum muaj 8 electrons. Atoms yuav nyiam nce, poob, lossis faib cov hluav taws xob kom ua tiav kev ruaj ntseg los ntawm kev muaj lub zog tag nrho sab nrauv (octest ruaj khov.)
Cov hlau puas muaj qib sab nraud tag nrho?
Reactivity of Alkaline Earth Metals
