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 number of neutrons is 22 (for the most stable isotope of argon, Ar-40) because you subtract the atomic mass from the atomic number then estimate! The most common isotop â¦ e of Argon, 40Ar, (comprising about 99.6% of all naturally occurring Argon) has 22 neutrons 18 electrons 18 protons. Argon has 24 known isotopes ranging from 30Ar (with 12 neutrons) to 53Ar (with 35 neutrons).
