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 element, uranium, has an atomic number of 92. That means that, assuming it's electrically neutral, it has 92 protons and 92 electrons. Since we know that this particular i â¦ sotope of uranium has a combined total of 238 protons and neutrons, the total number of neutrons in 238U is 238 - 92 = 146. Uranium 238 has: 92 protons, 92 electrons and 146 neutrons.
