Hauv qhov no, lub cim atomic rau ib lub atom nrog 82 protons thiab 125 neutrons yog dab tsi?
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 coj , thiab nws lub cim yog Pb.
dab tsi lub ntsiab muaj ib tug loj tus naj npawb ntawm 125? Tellurium
Tib neeg kuj nug, puas yog txhua lub atoms muaj neutrons?
Tag nrho cov ntsiab lus muaj atoms nrog neutrons tsuas yog ib. Ib txwm hydrogen (H) atom ua tsis yog muaj ib yam neutrons nyob rau hauv nws me me nucleus. Tus me me ntawd atom (qhov tsawg tshaj plaws ntawm tag nrho ) tsuas muaj ib tug electron thiab ib tug proton. Koj tuaj yeem tshem tawm cov hluav taws xob thiab ua ib qho ion, tab sis koj tsis tuaj yeem tshem tawm neutrons.
