The number of protons and electrons (in a neutral atom) are equal to the atomic number of the atom. For example in a, the number of protons and electrons in magnesium is 12.To find neutrons, you take the atomic mass of the atom and subtract the number of protons.For Magnesium, you subtract 12 from 25 to find the number of neutrons, which in this case is 13.he number of protons and electrons (in a neutral atom) are equal to the atomic number of the atom. For example in a, the number of protons and electrons in magnesium is 12.
