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.
