Isotopes yog txhais ua ntej los ntawm lawv lub caij thiab tom qab ntawd los ntawm cov lej ntawm cov protons thiab neutrons tam sim no. Carbon-12 (los yog 12C) muaj rau protons, rau neutrons, thiab rau electrons; Yog li ntawd, nws muaj ib tug loj tus naj npawb ntawm 12 amu (rau protons thiab rau neutrons).
Ntawm no, ib qho isotope tsim li cas?
Isotopes yog cov atoms ntawm tib lub caij uas muaj ntau tus lej ntawm neutrons tab sis tib tus naj npawb ntawm protons thiab electrons. Radioactive (tsis ruaj khov) isotopes muaj nuclei uas spontaneously lwj thaum lub sij hawm mus daim ntawv lwm yam isotopes.
Qhov thib ob, 3 piv txwv ntawm isotopes yog dab tsi? Qee qhov piv txwv ntawm ruaj khov isotopes yog isotopes carbon, potassium, calcium thiab vanadium. Xov tooj cua isotopes muaj qhov tsis ruaj khov ua ke ntawm protons thiab neutrons, yog li lawv muaj cov nuclei tsis ruaj khov. Vim cov no isotopes tsis ruaj tsis khov, lawv raug kev puas tsuaj, thiab hauv cov txheej txheem tuaj yeem tso tawm alpha, beta thiab gamma rays.
Piv txwv li, isotope thiab piv txwv yog dab tsi?
Kev txhais ntawm Isotopes . Cov ntsiab lus yog txhais los ntawm tus naj npawb ntawm protons hauv atomic nucleus. Rau piv txwv Ib qho atom nrog 6 protons yuav tsum yog carbon, thiab atom nrog 92 protons yuav tsum yog uranium. Ntxiv nrog rau cov protons, cov atoms ntawm yuav luag txhua lub caij tseem muaj cov neutrons.
Lub cim isotope yog dab tsi?
Lub nuclear cim muaj peb ntu: lub cim ntawm lub caij, tus lej atomic ntawm lub caij thiab cov lej loj ntawm qhov tshwj xeeb isotope . Ntawm no yog ib qho piv txwv ntawm nuclear cim : Lub ntsiab cim Li, yog li ntawd rau lithium. Tus naj npawb ntawm protons thiab neutrons nyob rau hauv lub nucleus ntawm lub atom.

Yuav ua li cas koj nthuav qhia cov txheeb cais nyob rau hauv ib daim ntawv qhia?
Cov txiaj ntsig piav qhia suav nrog ib lub rooj nrog cov ntaub ntawv txheeb xyuas tsim nyog xws li. qhov nruab nrab, hom, nruab nrab, thiab tus qauv sib txawv. Cov ntaub ntawv piav qhia yuav tsum muaj feem xyuam rau lub hom phiaj ntawm kev kawm; nws yuav tsum tsis txhob suav nrog rau lub hom phiaj ntawm nws. Yog tias koj tsis mus siv hom nyob qhov twg, tsis txhob suav nrog nws
Qhov loj spectrometry qhia tau hais tias muaj nyob ntawm isotopes li cas?
Isotopes muaj ntau atomic masses. Qhov txheeb ze ntawm txhua qhov isotope tuaj yeem txiav txim siab siv qhov loj spectrometry. Qhov loj spectrometer ionizes atoms thiab molecules nrog lub siab-zog electron beam thiab ces deflects ions los ntawm ib tug sib nqus teb raws li lawv loj-rau-them ratios (m / z m / z m / z)
Yuav ua li cas koj yuav tsum siv ib daim ntawv qhia txog lub npe tshuaj compound?
Yuav ua li cas koj yuav tsum siv ib daim ntawv qhia txog lub npe tshuaj compound? Txhawm rau sau npe los yog sau nws cov qauv, ua raws cov kab kos hauv cov duab 9.20 thiab 9.22 rau lub npe tiag tiag lossis qauv
Koj piav qhia txog daim ntawv qhia topographic li cas?
Daim duab qhia chaw saum toj saud feem ntau yog daim ntawv qhia loj loj uas piav qhia txog lub cev thiab tus txiv neej tsim ntawm toj roob hauv pes; thiab muaj qhov txawv txav los ntawm qhov pom ntawm cov kab contour uas qhia txog kev nthuav dav hauv av nyem ntawm thaj av
Daim duab qhia lub cev dawb qhia koj li cas txog lub zog net ntawm ib qho khoom?
Daim duab dawb-lub cev qhia cov vectors rau txhua lub zog ua haujlwm ntawm lub cev. Qhov tshwm sim vector pom los ntawm kev suav tag nrho tus kheej vectors sawv cev rau lub zog nqa. Txij li thaum F = ma, lub acceleration vector yuav taw tes rau hauv tib txoj kev raws li lub zog net, nrog rau qhov loj ntawm F / m
