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
