Lub npe Binary Molecular Compounds . Binary molecular compounds yog tshuaj sib xyaw uas muaj raws nraim ob lub ntsiab nonmetal. Thawj lub ntsiab yog muab nws lub npe lub npe; Qhov thib ob yog muab nws cov cag (hydr, bor, carb, ox, fluor, thiab lwm yam) ua raws li ide.

Yog li ntawd, binary molecular compounds yog dab tsi?

A binary molecular compound yog a molecular compound uas yog muaj li ntawm ob yam. Cov khoom sib xyaw ua ke binary molecular compounds yog ob qho tib si nonmetal atoms. Qhov no sib piv nrog ionic tshuaj sib xyaw , uas yog tsim los ntawm ib tug hlau ion thiab ib tug nonmetal ion.

Tom qab ntawd, lo lus nug yog, HF yog dab tsi yog qhov sib xyaw binary? Qee yam binary acids muaj xws li: HF (g) = hydrogen fluoride -> HF (aq) = hydrofluoric acid. HBr (g) = hydrogen bromide -> HBr (aq) = hydrobromic acid.

Hauv qhov no, qhov txawv ntawm binary ionic thiab binary molecular compounds yog dab tsi?

Ionic binary compounds muaj cov hlau cation thiab anion ua los ntawm cov nonmetal lossis polyatomic anion thaum Binary molecular compounds muaj ob los yog ntau tshaj nonmetals sib txuas covalently. Tsis muaj ions tam sim no vim cov atoms sib koom electrons. Prefixes yog siv los qhia tus naj npawb ntawm atoms ntawm txhua yam tam sim no.

Cov qauv rau cov tshuaj molecular sau li cas?

A molecular formula muaj cov cim tshuaj lom neeg rau cov ntsiab lus ua raws li cov lej sau npe piav qhia txog tus lej ntawm atoms ntawm txhua lub ntsiab lus tam sim no hauv molecule . Lub empirical qauv sawv cev rau qhov yooj yim tshaj plaws tag nrho-tus lej piv ntawm atoms hauv a compound.
