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.
