The following table shows the atomic nuclei that are isotonic (same neutron number N = 14) and isobaric (same nucleon number A = 26) with Magnesium-26. Naturally occurring isotopes are marked in green; light green = naturally occurring radionuclides.

The two following tables list the most important data and properties of the Magnesium isotopes. Further information on the individual Magnesium isotopes is listed on separate pages and can be accessed via the link in column 1.

Isotopic Data of Magnesium. An overview of the nuclides as well as the isotopic data and properties are listed on the following page: Magnesium isotopes. Chemistry of Magnesium

Magnesium-25 is a stable isotope of the chemical element magnesium, which has 13 neutrons in its atomic nucleus in addition to the element-specific 12 protons; the sum of the number of these atomic nucleus building blocks results in a mass number of 25.

Magnesium-24 is a stable isotope of the chemical element magnesium, which has 12 neutrons in its atomic nucleus in addition to the element-specific 12 protons; the sum of the number of these atomic nucleus building blocks results in a mass number of 24.
