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.

Yuav ua li cas tshwm sim rau ib yam khoom kab rov tav tshaj tawm thaum nws nyob hauv huab cua?
Yog tias cov khoom muaj qhov loj dua ntawm kab rov tav tshaj tawm, nws yuav mus deb dua thaum lub sijhawm nws nyob hauv huab cua, tab sis raws li qhov saum toj no ob qhov sib npaug qhia, lub sijhawm nws siv hauv huab cua tsis yog nyob ntawm tus nqi ntawm nws txoj kab rov tav tshaj tawm
Yuav ua li cas tshwm sim thaum methane hlawv hauv huab cua?
Ua tiav combustion tshwm sim thaum cov hydrocarbon hlawv hauv huab cua ntau dhau. Cov huab cua ntau dhau txhais tau hais tias muaj ntau dua cov pa oxygen txaus ua rau tag nrho cov pa roj carbon monoxide hloov mus rau carbon dioxide. Cov roj methane kub hnyiab nrog cov nplaim xiav ntshiab. Cov tshuaj tiv thaiv yog exothermic (nws muab tawm cua sov)
Yuav ua li cas oxygen tshwm sim hauv xwm piav qhia txog lub voj voog oxygen hauv qhov xwm txheej?
Piav lub voj voog oxygen hauv qhov xwm txheej. Oxygen muaj nyob rau hauv ob hom sib txawv hauv qhov xwm txheej. Cov ntaub ntawv no tshwm sim raws li cov pa roj carbon monoxide 21% thiab ua ke hauv daim ntawv oxides ntawm hlau thiab nonmetals, nyob rau hauv lub ntiaj teb crust, cua thiab dej. Oxygen rov qab mus rau qhov chaw los ntawm cov txheej txheem hu ua photosynthesis
Qhov txheej twg yog huab cua tshwm sim feem ntau tshwm sim?
Troposphere. Lub troposphere (los ntawm Greek: tropein - hloov, ncig lossis sib xyaw) yog txheej qis tshaj plaws ntawm lub ntiaj teb huab cua. Feem ntau ntawm huab cua phenomena, systems, convection, turbulence thiab huab tshwm sim nyob rau hauv no txheej, tab sis tej zaum yuav mus rau hauv lub qis feem ntawm thestratosphere
Vim li cas qee cov ntsiab lus pom zoo li diatomic molecules hauv qhov xwm txheej?
Diatomic cov ntsiab lus yog tag nrho cov gases, thiab lawv formmolecules vim hais tias lawv tsis muaj tag nrho valence plhaub ntawm lawv tus kheej. Cov ntsiab lus diatomic yog: Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, thiab Fluorine. Txoj hauv kev toremember lawv yog: BrINClHOF thiab Tsis Txhob Ntshai Ice ColdBeer
