WebThe number of protons in an isotope atom does not change but the number of neutrons does. The neon atom has more than seventeen isotopes. Such as 15 Ne, 16 Ne, 17 Ne, 18 Ne, 19 Ne, 20 Ne, 21 Ne, 22 Ne, 23 Ne, 24 Ne, 25 Ne, 26 Ne, 27 Ne, 28 Ne, 29 Ne, 30 Ne, 31 Ne, 32 Ne, 33 Ne and 34 Ne. WebThe atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a yttrium atom has thirty-nine protons and thirty-nine electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons.
