Kev piav qhia: Lub isotope ntawm lub caij X yog muab los ntawm AZX, qhov twg Z yog tus lej proton ntawm lub caij thiab A yog tus lej ntawm lub caij. Tus lej ntawm cov isotope no yuav yog 82 + 125 = 207 units, thaum nws muaj 82 protons. Saib ntawm lub rooj zaum, lub ntsiab lus 82 yog txhuas, thiab nws cov cim yog Pb.
Hais txog qhov no, dab tsi yog lub cim isotope rau atoms uas muaj 2 protons thiab 1 neutron?
Kev piav qhia: Helium-3 muaj 2 protons thiab 1 neutron.
Tsis tas li ntawd, lub caij twg muaj 86 electrons 125 neutrons thiab 82 protons them atom?
