WebMar 30, 2024 · The atomic number (number of protons) is a subscript at the lower left of the symbol of the element. The mass number (sum of the protons and neutrons) is a superscript to the upper left of the element symbol. For example, the nuclear symbols of the element hydrogen are: 11 H, 21 H, 31 H. Pretend that the superscipts and subscripts … WebFinding the Number of Neutrons. The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. Both of these numbers can be found on the periodic table. The atomic number is listed above the symbol of the element whereas the mass number is placed below. Let’s keep using oxygen as our example.
WebSep 2, 2024 · The element symbol for oxygen is O and its atomic number is 8. The mass numbers for oxygen must be 8 + 8 = 16; 8 + 9 = 17; 8 + 10 = 18. The nuclear symbols are written this way (again, pretend the superscript and subscript are sitting right on top of each other beside the element symbol): 168 O, 178 O, 188 O. Or, you could write:
