Cov ' txheeb ze abundance ' ntawm ib qho isotope txhais tau hais tias feem pua ntawm cov isotope tshwj xeeb uas tshwm sim hauv qhov xwm txheej. Cov ntsiab lus feem ntau yog tsim los ntawm kev sib xyaw ntawm isotopes. Cov lej ntawm cov feem pua ntawm cov isotopes tshwj xeeb yuav tsum ntxiv txog 100%. Cov kwv tij atomic mass yog qhov hnyav nruab nrab ntawm cov isotopic masses.

Ib yam li ntawd, dab tsi yog qhov txheeb ze ntawm isotopes hauv chemistry?

Cov ntsiab lus tseem ceeb: Atoms uas muaj tib tus naj npawb ntawm protons tab sis sib txawv ntawm cov neutrons hu ua isotopes . Isotopes muaj qhov sib txawv atomic masses. Cov txheeb ze abundance ntawm ib isotope yog qhov feem pua ntawm cov atoms nrog ib qho tshwj xeeb atomic loj pom nyob rau hauv ib qho piv txwv tshwm sim ntawm ib lub caij.

Tsis tas li ntawd, dab tsi yog qhov kev nplua nuj hauv chemistry? Kev nplua nuj ntawm tshuaj cov ntsiab lus. Los ntawm Wikipedia, dawb encyclopedia. Cov kev nplua nuj ntawm tshuaj cov ntsiab lus yog ib qho kev ntsuas ntawm qhov tshwm sim tshuaj cov ntsiab lus txheeb ze rau tag nrho lwm cov ntsiab lus hauv ib puag ncig muab.

Ntawm no, dab tsi yog txheeb ze abundance ntawm ib lub caij?

General formula rau txheeb ze abundance yog (M1)(x) + (M2)(1-x) = Me, qhov twg kuv yog atomic mass ntawm lub keeb Los ntawm lub sij hawm lub sij hawm, M1 yog qhov loj ntawm cov isotope uas koj paub kev nplua nuj ,x yog txheeb ze abundance ntawm cov isotope paub, thiab M2 yog qhov loj ntawm isotope tsis paub kev nplua nuj.

Dab tsi yog qhov txawv ntawm feem pua kev nplua nuj thiab cov txheeb ze kev nplua nuj?

Cov sib txawv ntawm cov txheeb ze abundance thiab feem pua abundance yog tias txheeb ze abundance hais txog tus naj npawb ntawm cov khoom qab zib koj siv hauv sim, qhov twg raws li cov Feem pua kev nplua nuj yog xa mus rau ntau npaum li cas ntawm cov khoom qab zib muaj nyob rau hauv txhua puas candies.
