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.
Magnesium has 12 electrons and protons; the number of neutrons is specific for each isotope.
Number of neutrons in a magnesium isotope = Mass number - 12

Subatomic particles with no charges are neutrons
subatomic particles make up the molecule
All elements are different from each other, that is why they are called elements. They have a different number of subatomic particles making them different.
Both Democritus' and John Dalton's atomic models had no subatomic particles.
Like all other atoms it contains three subatomic particles, they are Protons, Neutrons and Electrons.

Subatomic particles with no charges are neutrons
All subatomic particles have mass.
Subatomic particles are: neutron, proton, electron.
Everything is made of subatomic particles.

The only subatomic particles that exist in an atom are protons, neutrons, and electrons.
subatomic particleIn physics or chemistry, subatomic particles are the small particles composing nucleons and atoms. There are two types of subatomic particles: elementary particles, which are not made of other particles, and composite particles.
subatomic particles make up the molecule
Yes, atoms contain subatomic particles.
Molecules contain atoms and these atoms contain subatomic particles.
