the best answer is 12
24, it's the number of protons and neutrons, i.e. the number of sub-atomic particles in the nucleus.
Anywhere from 36 to 38, however, this is assuming you are talking about neutral atoms. The variation comes from the different stable isotopes of Magnesium, of which there are three.
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
A nucleus of uranium-238 contains 146 neutrons.
There are 77 Neutrons in the nucleus of one atom of Xenon

The isotopes of magnesium differ in their number of neutrons. Magnesium has three stable isotopes: magnesium-24, magnesium-25, and magnesium-26, with varying numbers of neutrons in their nucleus.
Any atom of magnesium will have 12 protons.Neutral atoms of Mg-24 will have 12 neutrons and 12 electrons. Mg-25 has 13 neutrons and Mg-26 has 14 neutrons. A magnesium ion will have either 10 or 11 electrons.
In an atom protons and neutrons are located in the atomic nucleus.
All the isotopes have a different number of neutrons in the nucleus.

The second nucleus of sodium contains 11 protons and 12 neutrons, while the second nucleus of magnesium contains 12 protons and 12 neutrons. These nuclei contribute to the overall stability and reactivity of the atoms.
There are three stable isotopes of the Magnesium atom.A,B These stable isotopes have atomic masses (the number of protons and neutrons in the atom's nucleus) ranging from 24 to 26.A,B In all cases they have an atomic number (number of protons in the nucleus) equal to 12.A As such the Magnesium nucleus does not always contain 12 protons and 12 neutrons. Approx. 79% of all naturally occurring Magnesium is 24Mg with 10% being 25Mg and another 11% occurring as 26Mg.A See the related links for more details.

The main difference between magnesium-24 and magnesium-25 is their atomic mass. Magnesium-24 has 24 protons and neutrons in its nucleus, while magnesium-25 has 25 protons and neutrons. This difference in atomic mass results in different physical and chemical properties between the two isotopes.
