Making the world better, one answer at a time. 25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
If you know the mass number and atomic number of the atom, the number of neutrons is just the difference between them. For example, in a carbon-13 atom, the atomic number is six and the mass number is thirteen, so the number of neutrons is seven.There are 12 neutrons in an atom of 22 10 Ne.or example, the number of neutrons in the most common isotope of lithium (atomic weight 6.941 amu and atomic number 3) is 7-3 = 4. Experimentally, the mass numbers are determined by mass spectrometry. The element is ionized, accelerated in an electric field, and then passed through a strong magnetic field.
