Tritium yog tib qho ntawm peb cov hydrogen isotopes uas yog xov tooj cua. Cov khoom siv hluav taws xob xws li tritium yuav hloov pauv mus rau hauv ib qho atom sib txawv hauv cov txheej txheem hu ua radioactive decay.
Yuav ua li cas isotope ntawm hydrogen yog cov xov tooj cua tshaj plaws?
Nws muaj ib qho hluav taws xob, ib qho proton thiab ob lub neutrons hauv nws. Txij li thaum, tus naj npawb ntawm cov neutrons ntau dua li cov protons hauv tritiumuas ua rau cov nucleus tsis ruaj khov, yog li tritium yog cov xov tooj cua ntawm cov isotope ntawm hydrogen thiab nws yuav dhau mus rau cov hluav taws xob tawg.
Yuav ua li cas yog isotope ntawm hydrogen tsis muaj hluav taws xob?
Deuterium (2H) Nws suav nrog 1 proton thiab 1 neutron hauv nws cov nucleus. Lub nucleus ntawm hydrogen 2 yog hu ua deuteron. Nws tsis yog xov tooj cua.
hom isotopes yog cov xov tooj cua dab tsi?
Muaj plaub hom hluav taws xob muab tawm los ntawm cov hluav taws xob atoms: Alpha hais. Beta hais. Gamma rays.
Thaum uranium-238 decays, nws tsim ob peb isotopes ntawm:
- Thorium.
- Radium.
- Radon.
- Bismuth.
Qhov twg ntawm cov isotopes yog cov xov tooj cua thiab yog vim li cas?
Raws li txoj kev xav, Yog tias qhov piv ntawm neutrons rau protons ntau dua ib qho, lossis dhau los ua loj heev, cov isotope yog cov xov tooj cua lossis tus lej atomic siab dua 83, cov isotope yuav yog radioactive. ib tug nuclide yog xov tooj cua yog tias nws lwj liberates zog.

Yuav ua li cas yog isotope ntawm hydrogen muaj nyob rau hauv cov dej hnyav?
Dej Hnyav (D 2 O) lossis deuterium oxide yog tsim los ntawm ob lub atom ntawm deuterium thiab ib atom ntawm oxygen. Deuterium yog ib qho isotope ruaj khov ntawm hydrogen nrog ob npaug ntawm qhov loj ntawm hydrogen vim muaj cov neutron ntxiv hauv nws cov nucleus.
Yuav ua li cas yog isotope ntawm uranium yog fissionable?
Fission reactors haus cov fissile isotope ib txwm tshwm sim, uas yog, U-235 Fission tshwm sim los ntawm kev nqus ntawm qeeb (thermal) neutrons. Uranium ores muaj cov isotope faib hauv qab no: 6 × 10 - 5 ntawm U-234, 7.11 × 10 - 3 ntawm U-235, thiab 0.
Nyob rau hauv alpha lwj ntawm txawv radioactive nuclides?
Nyob rau hauv alpha lwj ntawm cov xov tooj cua sib txawv, lub zog ntawm alpha hais tau muab piv. Nws tau pom tias thaum lub zog ntawm alpha particle nce ib nrab-lub neej ntawm kev lwj mus zuj zus . Nyob rau hauv qhov nuclides yog alpha decay feem ntau?
Yuav ua li cas kom vaporize hydrogen peroxide hauv tsev?
Vaporized hydrogen peroxide (VHP) txheej txheem kom tsis muaj menyuam Sterilization chamber siab txo kom lub tshuab nqus tsev siab heev. Liquid H 2 O 2 hloov ua vapor. Nyob rau hauv lub tshuab nqus tsev siab, vapors sau lub chamber, tiv tauj txhua qhov chaw.
Yuav nyeem cov cim isotope li cas?
Sau lub cim rau ib qho isotope, tso tus lej atomic ua tus lej thiab tus lej loj (protons ntxiv rau neutrons) ua tus sau rau sab laug ntawm lub cim atomic Tus Cov cim rau ob lub isotopes tshwm sim ntawm cov tshuaj chlorine tau sau raws li hauv qab no:
