How many protons and neutrons are in astatine
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. Web6 mrt. 2024 · The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of …
