Tsim ib qho Ion Qhov kev sib pauv hluav taws xob no ua rau muaj kev cuam tshuam ntawm electrostatic ntawm ob lub atom hu ua ionic bond ionic bond Ionic bonds form thaum lub nonmetal thiab hlau pauv electrons, thaum covalent bonds tsim thaum electrons sib koom ntawm ob nonmetals. … Ib daim ntawv cog lus cog lus muaj ib khub ntawm cov hluav taws xob sib koom ntawm cov atoms. Atoms tsim covalent daim ntawv cog lus kom ncav cuag lub xeev ruaj khov. https://courses.lumenlearning.com › tshooj › hom-of-bonds

. Ib lub atom uas poob ib los yog ntau tshaj valence electrons los ua ib tug zoo charged ion yog hu ua ib tug cation, thaum lub atom uas tau txais electrons thiab ua negatively them yog hu ua ib tug anion.
Thaum lub atom nruab nrab nce ib lossis ntau dua electrons nws hu ua dab tsi?
A cation (ib qho zoo ion) tsim thaum lub atom nruab nrab poob ib lossis ntau dua electrons los ntawm nws lub plhaub valence, thiab anion (ib qho tsis zoo ion) tsim thaum lub atom nruab nrab nce ib lossis ntau dua electrons hauv nws lub plhaub valence.
Yuav ua li cas rau lub atom yog tias nws nce ib lossis ntau dua electrons?
Ib lub atom uas nce lossis poob ib qho hluav taws xob ua an ion. Yog tias nws tau txais ib qho hluav taws xob tsis zoo, nws dhau los ua qhov tsis zoo ion. Yog tias nws poob ib qho hluav taws xob nws dhau los ua ib qho zoo ion (saib nplooj 10 kom paub ntxiv txog ions).
Valence Electron Configuration When Atoms Gain One or More Electrons

Puas yuav phosphorus nce lossis poob electrons?
Phosphorus nyiam poob 5 electrons thiab nce 3 electrons kom tiav nws octet . YPuas phosphorus nce electron? Luckily, txhua phosphorus atom tab tom nrhiav kom nce peb lub electrons. Nws yog kev sib tw zoo meej! Txawm li cas los xij, ib yam dab tsi yuav tsum tau pom, saib seb lawv muaj kev sib raug zoo nrog rau 6 electrons.
Dab tsi yog qhov kev piav qhia zoo tshaj plaws ntawm kev ua tswv cuab hauv ntau ntau?
Yuav muaj ntau caum (aka tenancy in sever alty) yog thaum vaj tse yog tswv los ntawm ib tug neeg los yog ib tug raws li txoj cai, muab tus tswv nrog tag nrho cov tswj av Tus Lub npe yog muab los ntawm qhov tseeb tias tus tswv yog "severed"
Puas yog kev sau ntau ntau lossis ntau yam?
Cov npe suav tuaj yeem suav tau lossis suav tsis tau. Feem ntau, feem ntau siv, cov ntsiab lus,ntau daim ntawv kuj tseem yuav muaj cov ntsiab lus Txawm li cas los xij, hauv cov ntsiab lus tshwj xeeb, ntau daim ntawv kuj tuaj yeem yog cov khoom sib xws xws li.
Puas sulfur nce lossis poob electrons?
Ntau cov atoms nonmetal, suav nrog cov sulfur, zoo li tsim cov anions, uas txhais tau tias lawv gain, tsis plam electrons, kom puv nws octet . Puas leej faj xav kom nce lossis poob electrons? Sulfur yuav xav tau nce 2 electrons txhawm rau ua tiav qhov kev teeb tsa octet.
Puas argon nce lossis poob electrons?
Cov pa roj carbon monoxide tsis muaj zog, vim tias lawv cov khoom siv hluav taws xob sab nrauv puv nkaus. Lub plhaub tag nrho ntawm cov khoom siv hluav taws xob sab nraud yog qhov tshwj xeeb ruaj khov. Qhov no txhais tau hais tias noble gas atoms tsis nce lossis poob electronsyooj yim;
