Isotopes of magnesium (12Mg) Mg. There are 19 radioisotopes that have been discovered, ranging from 18. Mg). The longest-lived radioisotope is 28. Mg with a half-life of 20.915 (9) h. The lighter isotopes mostly decay to isotopes of sodium while the heavier isotopes decay to isotopes of aluminium. The shortest-lived is proton-unbound 18.
Magnesium has three stable isotopes: 24 Mg, 25 Mg and 26 Mg. All are present in significant amounts in nature (see table of isotopes above). About 79% of Mg is 24 Mg. The isotope 28 Mg is radioactive and in the 1950s to 1970s was produced by several nuclear power plants for use in scientific experiments. This isotope has a relatively short half ...
List of elements by stability of isotopes. Isotope half-lives. The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. This is a list of chemical elements by the stability of their isotopes. Of the first 82 elements in the periodic table, 80 have isotopes considered to ...
Table of nuclides. A table or chart of nuclides is a two-dimensional graph of isotopes of the elements, in which one axis represents the number of neutrons (symbol N) and the other represents the number of protons (atomic number, symbol Z) in the atomic nucleus. Each point plotted on the graph thus represents a nuclide of a known or ...
Aluminium-26 (26Al, Al-26) is a radioactive isotope of the chemical element aluminium, decaying by either positron emission or electron capture to stable magnesium -26. The half-life of 26 Al is 717,000 years. This is far too short for the isotope to survive as a primordial nuclide, but a small amount of it is produced by collisions of atoms ...
Isotopes of sodium. Na is the only stable (and the only primordial) isotope. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2). Sodium has two radioactive cosmogenic isotopes (22. Na, with a half-life of 14.9560 (15) h). With the exception of those two isotopes, all other isotopes have half-lives ...

Magnesium is an essential element in biological systems. Magnesium occurs typically as the Mg 2+ ion. It is an essential mineral nutrient (i.e., element) for life [1][2][3][4] and is present in every cell type in every organism. For example, adenosine triphosphate (ATP), the main source of energy in cells, must bind to a magnesium ion in order ...
