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.
The Mass Number of an element is equal to the protons added to the neutrons. The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23. Therefore. An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons.
