Ntawm STP, fluorine yog cov roj thiab bromine yog cov kua vim tias, piv rau fluorine, bromine muaj (1) cov ntawv cog lus muaj zog dua. (2) muaj zog intermolecular rog.
Vim li cas fluorine yog roj ntawm STP?
Nyob rau hauv fluorine, cov electrons yog nruj nreem kaw rau lub nuclei Cov electrons muaj sij hawm me ntsis mus rau ib sab ntawm lub molecule, yog li London dispersion rog kuj tsis muaj zog. … Thaum qhov kub tsis txaus, cov molecules tag nrho yuav yog cov khib nyiab. Ntawm qhov kub txaus lawv tag nrho yuav gases.
Vim li cas fluorine yog roj bromine ua kua thiab iodine ib yam khoom ntawm chav tsev kub?
Muaj Vander Waals tsis muaj zog uas muaj nyob nruab nrab ntawm cov molecules ntawm fluorine, bromine, thiab iodine…. Whereas bromine muaj qhov hnyav dua molecular dua li fluorine thiab lub zog ntawm lub zog ntawm lub cev yuav ntau dua fluorine thiab yog li ntawd tshwm sim ua kua hauv chav tsev kub.
nqe lus twg piav qhia yog vim li cas br ob yog kua ntawm STP thiab kuv ob yog ib qho khoom ntawm STP?
nqe lus twg piav qhia vim li cas Br2 yog kua ntawm STP thiab I2 yog cov khoom ntawm STP? … Molecules ntawm Br2 muaj zog intermolecular zog dua li cov molecules ntawm I₂. 4. Molecules ntawm I₂ muaj zog intermolecular zog dua molecules ntawm Br2.
Vim li cas bromine yog kua?
Bromine yog kua vim cov rog sib xyaws muaj zog txaus kom nws tsis vaporise. Br cov ntaub ntawv diatomic molecules thiab van der Waals kev sib cuam tshuam muaj zog txaus.
