Cov qauv ntawm ib lub caij nrog cov neutrons sib txawv muaj ntau qhov sib txawv thiab hu ua isotopes. Qhov nruab nrab atomic loj rau ib lub caij yog xam los ntawm kev suav cov huab hwm coj ntawm lub caij isotopes, txhua qhov sib npaug los ntawm nws qhov kev nplua nuj nyob hauv ntiaj teb.
Puas isotopic mass tib yam li atomic mass?
Txhua isotope muaj nws tus kheej atomic mass, hu ua nws isotopic mass. … Tsis tas li ntawd, qhov txheeb ze isotopic mass tsis zoo ib yam li isotopic mass, thiab txheeb ze atomic mass (tseem hu ua atomic hnyav) tsis zoo ib yam li atomic mass. Ib qho txheeb ze isotopic loj yog qhov loj ntawm ib qho isotope txheeb ze rau 1/12 ntawm qhov loj ntawm carbon-12 atom.
Yuav ua li cas isotopes cuam tshuam nrog atomic mass?
Txhua isotope ntawm ib lub ntsiab lus muaj tib tus lej atomic tab sis tus lej sib txawv (A), uas yog qhov suav ntawm cov lej ntawm cov protons thiab neutrons. … Lub atomic mass ntawm ib lub caij yog qhov hnyav nruab nrab ntawm cov pawg ntawm cov isotopes uas tshwm sim lawm.
Puas isotopes muaj tib tus lej atomic?
Atoms ntawm tib lub caij muaj tib tus lej ntawm protons, tab sis txawv isotopes muaj cov lej sib txawv ntawm cov neutrons. Cov isotopes sib txawv ntawm tib lub caij muaj ntau qhov sib txawv vim lawv muaj ntau tus lej ntawm neutrons.
Yuav puas isotopes puas puas muaj tib tus lej piav qhia?
Isotopes sib txawv ntawm tib lub caij tsis tuaj yeem muaj tib tus lej, tab sis isotopes ntawm cov ntsiab lus sib txawv feem ntau muaj tib tus lej, piv txwv li, carbon-14 (6 protons thiab 8 neutrons) thiab nitrogen-14 (7 protons thiab 7 neutrons).

Puas yog molecular mass thiab molar mass tib yam?
Ntxiv mus, qhov sib txawv tseem ceeb ntawm ob qho tib si yog qhov molar loj muab qhov loj ntawm mole ntawm ib yam khoom. Qhov hnyav molecular yog qhov loj ntawm ib qho molecule ntawm ib yam khoom. Thaum lub ntsiab lus thiab units txawv rau molar mass thiab molecular hnyav, tus nqi yog tib yam Qhov txawv ntawm molar mass thiab molecular mass yog dab tsi?
Puas yog lub foob pob atomic yog kev ua tsov ua rog?
Peter Kuznick, tus thawj coj ntawm Nuclear Studies Institute ntawm American University, tau sau los ntawm Thawj Tswj Hwm Truman Thawj Tswj Hwm Truman Truman tau coj kev tawm tsam rau pej xeem cov cai, kom muaj cai sib npaug ntawm cov tub rog rau kev ntxub ntxaug ntawm cov nom tswv dawb nyob rau sab qab teb.
Puas yog allotropes thiab isotopes tib yam?
Isotopes yog atoms uas muaj cov lej sib txawv ntawm cov neutrons dua li cov isotope sib txawv. Allotropes yog cov muaju uas muaj cov qauv atomic sib txawv dua li cov allotrope sib txawv. Dab tsi yog qhov txawv ntawm allotropes thiab isomers?

MySQL - atomic operations and transactions Nyob hauv MySQL, txhua yam kev hloov kho yog atomic - qhov haujlwm no tuaj yeem ua tiav lossis ua tsis tiav, tab sis los ntawm kev tsim, nws yuav tsum tsis txhob ib nrab ua tiav los yog ib nrab poob.
Puas yog atomic absorption spectrophotometer?
Atomic absorption spectrophotometric tshuaj xyuas qhov concentration ntawm cov ntsiab lus hauv cov qauv ua kua raws li lub zog nqus los ntawm qee qhov wavelengths ntawm lub teeb(feem ntau 190 txog 900 nm). … Hauv atomic absorption spectrometry, ib qho qauv yog atomized, feem ntau yog los ntawm nplaim taws lossis graphite rauv, thiab tawg mus rau hauv lub teeb .
