Kuj nug, dab tsi atom muaj 20 neutrons?
Ib atom Chlorine-35 muaj 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) hos ib atom Chlorine-37 muaj 20 neutrons (17 protons + 20 neutron = 37 particles in then nucleus). Ntxiv los yog tshem tawm cov neutron ntawm ib qho atom cov nucleus tsim isotopes ntawm ib lub caij.
Tus naj npawb ntawm neutrons ntawm poov tshuaj yog dab tsi?
Potassium -40 - Nws muaj 19 protons andatomic mass yog 40. Yog li ntawd, tus naj npawb ntawm neutrons yog 40-19 uas yog 21. Potassium -41 - Nws muaj 19 protons andatomic mass yog 41. Yog li ntawd, tus naj npawb ntawm neutrons yog 41-19 uas yog 22.
