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.
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.
txhais li cas los ntawm unpaired electrons?
Ib qho tsis muaj hluav taws xob yog ib lub tshuab hluav taws xob uas nyob ib puag ncig ntawm ib lub atom los ntawm nws tus kheej, tsis yog ib feem ntawm ib khub electron.
Dab tsi yog qhov sib txawv ntawm khub thiab tsis ua khub electrons?
paired electrons yog electrons nyob rau hauv ib lub atom uas tshwm sim nyob rau hauv lub orbital li khub whereas unpaired electrons yog lub electrons nyob rau hauv ib lub atom uas tshwm sim nyob rau hauv ib tug orbital ib leeg. … Qhov no yog qhov sib txawv nruab nrab ntawm kev ua khub thiab tsis ua khub electrons.
Yuav ua li cas yog tus naj npawb ntawm unpaired valence electrons nyob rau hauv ib lub atom?
Tus naj npawb ntawm Valence Electrons uas tsis sib xws hauv ib lub atom cuam tshuam li cas rau tus lej ntawm daim ntawv cog lus uas lub atom tuaj yeem tsim tau? Lubntawm unpaired VAs yog tib tus lej ntawm daim ntawv cog lus uas yuav tsim… K, vim lub atom muaj ib qho hluav taws xob ntxiv, ntau dua li cov ion. Ob lub fluorine atoms koom ua ke los tsim ib daim ntawv cog lus.

Dab tsi yog qhov tsis sib xws?
- Comments. Warping zoo unwraps ib daim duab txog nws qhov chaw tig concentric nta (xws li diffraction rings) rau hauv kab txaij ntsug hauv daim duab duab plaub. Qhov no muaj txiaj ntsig zoo rau kev ntsuas ntawm thaj tsam annular ntawm cov duab, uas tsis muaj DM muaj nuj nqi.
Ntawm qhov sib npaug ntawm qhov sib npaug ntawm cov reactants) thiab cov khoom) yog qhov tas li?
Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine.
Yuav ua li cas ua cov feem tsis sib xws rau feem zoo sib xws?
Mua ob ntu ntawm txhua feem los ntawm tus lej ntawm lwm feem, yog tias tus lej sib txawv. Piv txwv li, yog tias koj ntxiv 1/3 thiab 2/5, muab ob qho tib si 1 thiab 3 los ntawm 5, ua cov feem 5/15. Tom qab ntawd muab ob qho tib si 2 thiab 5 los ntawm 3 (tus denominator ntawm lwm feem), ua tus feem 6/15 .
Dab tsi ntawm cov hauv qab no yog cov lus hloov pauv rau qhov tsis sib xws?
Cov lus hloov pauv tuaj yeem siv los taw qhia qhov tsis sib xws, kev txwv lossis qhov tsis pom kev pom: Rather than. Txawm tias qhov no yuav muaj tseeb. Ntawm qhov tsis sib xws. Kev sib piv. Txhob Cia Siab. Kev muaj tiag. Thiab dua.
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
