Web6 mrt. 2024 · To find the number of neutrons, you will need to subtract the atomic number from the atomic mass. Remember that the atomic number is the same as the number of protons, which you have already identified. [6] For our boron example, 11 (atomic mass) – 5 (atomic number) = 6 neutrons. Part 2. WebArsenic is a chemical element with atomic number 33 which means there are 33 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
