txiv kab ntxwv thiab xiav nuclides tsis ruaj khov, nrog cov squares dub ntawm cov cheeb tsam no sawv cev rau cov nuclides ruaj khov. Cov kab nruam dhau mus rau hauv qab feem ntau ntawm cov nuclides suav nrog cov haujlwm ntawm daim duab ntawm (feem ntau yog hypothetical) nuclides uas tus lej proton yuav zoo ib yam li neutron tooj.
Koj paub li cas yog tias lub caij ruaj khov lossis tsis ruaj khov?
Ib atom yog stable yog tias cov rog ntawm cov khoom uas pleev lub nucleus yog sib npaugIb lub atom tsis ruaj khov (xov tooj cua) yog tias cov rog no tsis sib npaug; yog hais tias lub nucleus muaj ntau tshaj ntawm lub zog sab hauv. Instability ntawm atom lub nucleus yuav tshwm sim los ntawm ntau tshaj ntawm neutrons los yog protons.
Puas nuclides tsis ruaj khov?
Nuclides yuav ruaj khov lossis tsis ruaj khov. … Hais txog 1700 nuclides paub, ntawm uas muaj txog 300 nyob ruaj khov thiab cov xov tooj cua ntxiv. Qhov tshwm sim ntawm kev lwj ntawm cov nuclides tsis ruaj khov nrog kev tso tawm ntawm cov khoom los yog photons yog cov txheej txheem txheeb cais hu ua radioactive decay.
Dab tsi yog daim ntawv tsis ruaj khov ntawm lub ntsiab?
Ib qho atom tsis ruaj khov muaj ntau lub zog sab hauv, nrog rau qhov tshwm sim uas lub nucleus tuaj yeem hloov pauv hloov pauv mus rau daim ntawv ruaj khov dua. Qhov no hu ua ' radioactive decay'. … Cov isotopes tsis ruaj khov (uas yog cov xov tooj cua zoo li no) hu ua radioisotopes. Qee lub ntsiab lus, xws li uranium, tsis muaj isotopes ruaj khov.
Puas isotopes tsis ruaj khov?
Atoms ntawm tib lub caij nrog cov lej sib txawv ntawm cov neutrons hu ua isotopes. … Cov isotopes no hu ua radioisotopes. Lawv cov nuclei tsis ruaj khov, yog li lawv tawg, lossis lwj, thiab tawm hluav taws xob.
