Pab pawg 18 cov ntsiab lus (helium, neon, thiab argon) muaj ib qho tag nrho sab nrauv, lossis valence, plhaub Ib lub plhaub valence tag nrho yog cov khoom siv hluav taws xob ruaj khov tshaj plaws. Cov ntsiab lus nyob rau hauv lwm pab pawg muaj ib feem ntawm valence shells thiab nce los yog poob electrons kom tiav ib tug ruaj khov electron configuration.
Puas neon valence plhaub puv?
Qee atoms tuaj yeem ruaj khov nrog octet txawm tias lawv lub plhaub valence yog 3n plhaub, uas tuaj yeem tuav txog 18 electrons. … Hauv cov lus no, koj tuaj yeem pom tias helium muaj lub plhaub valence tag nrho, nrog ob lub electrons hauv nws thawj zaug thiab nkaus xwb, 1n, plhaub. Ib yam li ntawd, neon muaj ua tiav txheej 2n plhaub uas muaj yim electrons
Neon muaj pes tsawg lub plhaub valence?
Neon, nrog nws cov teeb tsa xaus rau hauv s 2p6, muaj eight valence electrons.
Puas tsis muaj valence plhaub?
Txoj cai octet hais tias atoms tau ruaj khov tshwj xeeb tshaj yog thaum lawv cov valence plhaub tau txais tag nrho cov valence electrons. Piv txwv li, nyob rau hauv saum toj no, Helium (Nws) thiab Neon (Ne) muaj cov plhaub sab nraud uas muaj tag nrho, yog li tsis muaj kev nyiam nce lossis poob electrons.
Cov ntsiab lus twg muaj lub plhaub valence tag nrho?
Pab pawg 18 cov ntsiab lus (helium, neon, thiab argon)muaj tag nrho sab nrauv, lossis valence, plhaub. Lub plhaub valence tag nrho yog qhov ruaj khov tshaj plaws electron configuration.
