Hauv lwm lo lus, hauv txhua 100 tshuaj chlorine atoms, 75 atoms muaj ib tug loj tus naj npawb ntawm 35 , thiab 25 atoms muaj ib tug loj tus naj npawb ntawm 37. Qhov no yog vim lub tshuaj chlorine - 35 isotope ntau ntau dua tshaj qhov tshuaj chlorine -37 isotope cov. Lub rooj qhia cov lej loj thiab ntau ntawm cov tooj liab isotopes uas tshwm sim.

Tsis tas li ntawd, qhov twg chlorine muaj ntau dua?

Chlorine-35

Tsis tas li ntawd, yog vim li cas atomic mass ntawm chlorine coj li 35.5 U thiab tsis yog tag nrho cov lej zoo li 35 U lossis 36 U piav qhia? Cov tshuaj chlorine muaj ib khub ntawm isotopes nrog tib yam tus lej atomic 17 tab sis txawv loj 35 thiab 37.so peb coj lub atomic mass ntawm chlorine raws li qhov nruab nrab pawg ntawm 35 thiab 37.by xam peb yuav tau qhov nruab nrab li 35.5 .yog li, feem ntau peb coj chlorine loj raws li 35.5 ua .. Chlorine yog ib qho isotope nrog tus lej 17.

Yog li ntawd, qhov txawv ntawm chlorine 35 thiab chlorine 37 yog dab tsi?

Tus lej ntawm protons lub atom muaj, tseem hu ua atom tus lej atomic, txiav txim seb lub caij twg nws yog. Ib atom ntawm chlorine - 35 muaj 18 neutrons (17 protons + 18 neutrons = 35 cov khoom hauv nucleus) thaum lub atom ntawm chlorine - 37 muaj 20 neutrons (17 protons + 20 neutrons = 37 cov khoom hauv nucleus).

Koj yuav suav li cas feem pua ntawm cov tshuaj chlorine?

Kev daws:

  1. Chlorine-35: atomic huab hwm coj = 34.969amu thiab feem pua ntau = 75.77%
  2. Chlorine-37: atomic huab hwm coj = 36.966amu thiab feem pua kev nplua nuj = 24.23%
