Ib atom muaj tus lej ruaj khov orbits nyob rau hauv uas ib tug electron yuav nyob tsis muaj emission ntawm radiant zog. Txhua lub voj voog sib raug, mus rau ib theem zog. 4. Ib qho chaw tshwj xeeb nyob ib ncig ntawm lub nucleus uas muaj lub voj voog ntawm sib npaug zog thiab lub vojvoog tau hu ua lub plhaub.
Ntawm no, cov ntsiab lus tseem ceeb ntawm Bohr tus qauv atomic yog dab tsi?
Cov ntsiab lus tseem ceeb ntawm Bohr Qauv Electrons orbit lub nucleus hauv orbits uas muaj qhov loj me thiab lub zog. Lub zog ntawm lub orbit muaj feem xyuam rau nws qhov loj. Lub zog qis tshaj yog pom nyob rau hauv qhov tsawg tshaj plaws orbit. Radiation yog absorbed los yog emissions thaum lub electron txav ntawm ib lub orbit mus rau lwm qhov.
Ib yam li ntawd, electrons txav hauv Bohr tus qauv li cas? Cov qauv hais tias electrons hauv atoms txav nyob rau hauv ib ncig orbits nyob ib ncig ntawm lub hauv paus nucleus thiab tsuas tuaj yeem orbit stably nyob rau hauv ib co taag ncig orbits ntawm ib tug discrete set ntawm deb ntawm lub nucleus. Cov orbits no muaj feem xyuam nrog lub zog meej thiab tseem hu ua lub zog plhaub lossis qib zog.
Ntxiv mus, Bohr txoj kev xav ntawm atomic qauv yog dab tsi?
npe Physics. a txoj kev xav ntawm atomic qauv uas hydrogen atom ( Bohr atom ) yog assumed los ntawm ib tug proton li nucleus, nrog ib tug tib electron txav nyob rau hauv txawv ncig orbits nyob ib ncig ntawm nws, txhua lub orbit sib raug mus rau ib tug tshwj xeeb quantized zog lub xeev: lub kev xav tau txuas mus rau lwm qhov atoms.
5 atomic qauv yog dab tsi?
- Dalton qauv (Billiard pob qauv)
- Thomson qauv (Plum pudding qauv)
- Lewis qauv (Cubical atom qauv)
- Nagaoka qauv (Saturnian qauv)
- Rutherford qauv (Planetary qauv)

Dab tsi yog qhov hnyav tshaj plaws uas muaj tsawg kawg yog ib qho isotope ruaj khov?
Bismuth-209 (209Bi) yog lub isotope ntawm bismuth nrog ntev tshaj plaws paub ib nrab-lub neej ntawm ib tug radioisotope uas undergoes α-decay (alpha decay). Nws muaj 83 protons thiab cov khawv koob ntawm 126 neutrons, thiab atomic mass ntawm 208.9803987 amu (atomic mass units). Bismuth-209. General Protons 83 Neutrons 126 Nuclide data Ntuj abundance 100%
Dab tsi yog qhov chaw nyob ruaj khov nyob rau hauv nyias txheej chromatography?
Lub silica gel (los yog alumina) yog qhov chaw nres tsheb. Cov theem nyob ruaj khov rau nyias txheej txheej chromatography kuj feem ntau muaj cov khoom siv fluorescesin UV teeb - vim li cas koj yuav pom tom qab. Lub mobilephase yog cov kuab tshuaj uas tsim nyog los yog sib tov ntawm cov kuab tshuaj
Yam khoom twg tsis muaj qhov ruaj khov thiab tsis muaj qhov ntim ruaj khov?
Cov theem ntawm cov teeb meem uas tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog cov roj. Cov roj tsis muaj qhov ruaj khov
Nws hu li cas thaum cov khoom nyob hauv qhov chaw ruaj khov thiab vibrate ntawm qhov chaw?
Daim duab 2.1 Cov khoom nyob rau hauv cov khoom yog tsau rau lawv cov neeg nyob ze. Lawv vibrate ib ncig ntawm lawv txoj hauj lwm ruaj. Aerosols vam khom rau cov khoom khib nyiab, kua thiab roj thiab lawv coj li cas. Txoj kev xav uas piav txog qhov no yog Kinetic Theory of Matter
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
