Hauv chemistry, ib qho hluav taws xob tsis sib xws yog ib qho hluav taws xob uas nyob hauv lub orbital ntawm lub atom ib leeg, tsis yog ib feem ntawm ib khub electron. Txhua lub atomic orbital ntawm ib lub atom muaj peev xwm muaj ob lub tshuab hluav taws xob nrog qhov sib txawv.
txhais li cas yog tias ib qho hluav taws xob tsis sib xws?
Ib qho hluav taws xob tsis sib xws yog ib lub tshuab hluav taws xob uas nyob ib puag ncig ntawm lub atom los ntawm nws tus kheej, es tsis yog ib feem ntawm ib qho hluav taws xob … thaum muaj kev cuam tshuam ntawm ib qho chaw hu ua radical. Lawv ua, txawm li cas los xij, ua lub luag haujlwm tseem ceeb hauv kev piav qhia txog txoj kev tawm tsam.
Yuav ua li cas koj pom cov electrons tsis sib xws?
Rau nrhiav tus naj npawb ntawm cov hluav taws xob tsis sib xws, tom qab ntawd ua ntej peb muaj txhawm rau nrhiav tus lej atomic ntawm lub caij ces sau cov teeb tsa hauv av, tom qab ntawd raws li lub xeev oxidation rho tawm cov xov tooj ntawm electrons los ntawm lub plhaub sab nrauv. Yog li, muaj 4 yam tsis sib xws. Yog li, muaj 3 yam tsis sib xws.
Yuav ua li cas yog unpaired electron nrog piv txwv?
Cov piv txwv ruaj khov tshaj plaws ntawm cov hluav taws xob tsis sib xws muaj nyob ntawm atoms thiab ions ntawm lanthanides thiab actinides … Ib qho hluav taws xob tsis sib xws muaj lub sijhawm sib nqus dipole, thaum ib khub electron tsis muaj dipole lub sij hawm vim ob lub electrons muaj opposite spin yog li lawv cov magnetic dipole teb nyob rau hauv opposite lus qhia thiab tso tseg.
Yuav ua li cas yog ib khub los yog tsis ua khub electron?
paired electrons yog electrons nyob rau hauv ib lub atom uas tshwm sim nyob rau hauv lub orbital li khubwhereas unpaired electrons yog electrons nyob rau hauv lub atom uas tshwm sim nyob rau hauv ib tug orbital ib leeg. … Tsis tas li ntawd xwb, cov electrons ua ke ua rau cov diamagnetism ntawm atoms whereas lub unpaired electrons ua paramagnetism los yog ferromagnetism nyob rau hauv atoms.
