Bromine yog kua ntawm chav tsev kub vim bromine molecules muaj kev sib cuam tshuam intermolecular txaus nyob rau hauv cov xwm txheej kom nkag mus rau hauv
Ib yam li ntawd, vim li cas bromine yog kua?
Bromine yog a ua kua vim cov electrons zoo sib nrug ntawm cov nuclei yog li lawv yooj yim distorted. Intermediate intermolecular rog muaj nyob thiab yog li nws nyob hauv ua kua xeev.
Qhov thib ob, yog vim li cas bromine yog kua nyob rau hauv chav tsev kub thiab iodine yog ib qho khoom? Raws li peb txav los ntawm fluorine mus rau iodine , cov hluav taws xob txuas ntxiv los ntawm cov nuclei yog li cov huab cua hluav taws xob tuaj yeem cuam tshuam yooj yim dua. Lub London dispersion rog tau nce zuj zus. Nws tsuas yog nyob ntawm kub ntawm -7 ° C thiab 59 ° C uas fluorine thiab chlorine yog gases, bromine yog a khov kho , thiab iodine yog a khov kho.
Ib yam li ntawd, puas yog br2 kua ntawm chav tsev kub?
Bromine (Br, lub caij 35), kuj pom tau tias yog ib qho diatomic molecule (Br2), yog a kua ntawm chav tsev kub solidification ntawm -7.2ºC.
Yuav ua li cas rau bromine ntawm chav tsev kub?
Nws yog a ntom, reddish-xim av kua uas evaporates yooj yim ntawm chav kub rau a liab vapor a muaj zog, zoo li chlorine tsw. Bromine tsis tshua muaj reactive tshaj li chlorine los yog fluorine tab sis ntau reactive tshaj iodine. Nws tsim cov tebchaw nrog ntau lub ntsiab lus thiab, zoo li chlorine, ua raws li a tshuaj dawb huv.

Vim li cas ionic bonds khov ntawm chav tsev kub?
Ionic tebchaw muaj cov ntsiab lus siab melting thiab boiling, yog li lawv nyob rau hauv cov khoom nyob rau hauv chav tsev kub. Lub zog no overcomes lub zog electrostatic zog ntawm attraction uas ua nyob rau hauv tag nrho cov lus qhia ntawm tus oppositely them ions: ib co quab yuam tau kov yeej thaum lub melting
Lub xeev ntawm ionic compounds nyob rau hauv chav tsev kub yog dab tsi?
Covalent Bonds vs Ionic Bonds Covalent Bonds Ionic Bonds State nyob rau hauv chav tsev kub: kua los yog gaseous khoom polarity: Tsawg siab
Cov kua methanol lossis ethanol twg muaj qhov vapor siab dua ntawm chav tsev kub?
Methanol muaj qhov loj dua vapor siab nyob rau hauv chav tsev kub vim hais tias nws muaj qis molecular hnyav thaum piv nrog ethanol, uas txhais tau hais tias nws muaj zog intermolecular zog
Vim li cas cov kua siv lead ua kua hloov xim nrog kub?
Cov molecules hauv cov kua siv lead ua kua tuaj yeem txav mus los ntawm nws tus kheej, xws li hauv cov kua, tab sis nyob twj ywm me ntsis, xws li hauv cov khoom siv lead ua (khoom). Cov kua siv lead ua kua no teb rau kev hloov pauv ntawm qhov kub thiab txias los ntawm kev hloov xim. Raws li qhov kub thiab txias, lawv cov xim hloov ntawm liab mus rau txiv kab ntxwv, daj, ntsuab, xiav, thiab ntshav
Puas yog ionic bonds kua ntawm chav tsev kub?
Tag nrho cov ntsiab lus ionic tebchaw yog cov khoom ntawm chav tsev kub, txawm li cas los xij muaj chav kawm ntawm chav tsev kub ionic kua. [1] Cov no yog qhov tshwm sim ntawm kev sib koom ua haujlwm tsis zoo ntawm cov ions hauv daim ntawv
