tag nrho cov gases, thiab lawv tsim molecules vim lawv tsis muaj valence shells ntawm lawv tus kheej. Cov diatomic cov ntsiab lus yog : Bromine, Iodine, Nitrogen , Chlorine, Hydrogen, Oxygen , thiab fluorine. Cov tshuaj tsuas yog cov ntsiab lus uas yog ruaj khov ib atom molecules ntawm tus qauv kub thiab siab (STP) yog cov noble gases.

Ua raws li qhov no saib, vim li cas nitrogen muaj nyob ua ib qho diatomic molecule?

Nitrogen vim nws qhov me me muaj qhov nyiam tsim pπ-π ntau daim ntawv cog lus nrog nws tus kheej. Nitrogen yog li tsim ib tug ruaj khov heev Diatom molecule , N2. Ntawm kev txav mus rau ib pab pawg, qhov nyiam tsim pπ-pπ daim ntawv cog lus txo qis (vim qhov loj ntawm cov khoom hnyav dua).

Ib yam li ntawd, dab tsi yog diatomic molecule thiab yog vim li cas lawv nyob li no? Diatomic Compounds Ob peb lub tebchaw xws li carbon monoxide, hydrogen chloride thiab nitric oxide muaj Diatomic molecules . Zoo li lub diatomic cov ntsiab lus, cov no tshuaj sib xyaw yog gases ntawm chav tsev kub. Chemists hu cov no Cov tebchaw "heteronuclear" vim tias lawv cov atomic nuclei los ntawm cov ntsiab lus sib txawv.

Tsis tas li ntawd, puas muaj nitrogen nyob ua ib qho molecule diatomic?

Cov ntsiab lus tseem ceeb: Diatomic Cov ntsiab lus Diatomic cov ntsiab lus yog cov ntsiab lus ntshiab uas tsim molecules muaj ob lub atom sib txuas ua ke. Muaj xya diatomic khoom: hydrogen, nitrogen , oxygen, fluorine, chlorine, iodine, bromine. Cov ntsiab lus no muaj peev xwm nyob nyob rau hauv daim ntawv ntshiab nyob rau hauv lwm yam kev npaj.

Puas muaj cov pa roj carbon monoxide zoo li diatomic molecules?

Kev piav qhia: Hauv qhov xwm txheej ntawm atoms noble gases ua tsis khi nrog lwm tus cov pa los yog nrog ib leeg. Helium muaj nyob raws li atoms ntawm Helium tsis li Diatomic molecules . Helium ua tsis tsim cov tebchaw nrog atoms ntawm lwm cov ntsiab lus.
