WebTo calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number number of electrons = atomic number number of neutrons =... WebJun 26, 2024 · The atomic weight is calculated by adding the mass of each isotope multiplied by its fractional abundance. For example, for an element with 2 isotopes: atomic weight = mass a x fract a + mass b x fract b. If there were three isotopes, you would add a 'c' entry. If there were four isotopes, you'd add a 'd', etc.
