Splet06. mar. 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. SpletThe atomic number is not only equal to the number of protons in a nucleus of an element, it is also equal to the number of electrons because atoms are neutral: protons = electrons. The neutrons ...
