Magnesium is the ninth most abundant element in the universe.It is produced in large, aging stars from the sequential addition of three helium nuclei to a carbon nucleus.
Hundreds of enzymes require magnesium ions to function.
Magnesium compounds are used medicinally as common laxatives, antacids (e.g., milk of magnesia), and to stabilize abnormal nerve excitation or blood vessel spasm in such conditions as eclampsia.
Organomagnesium compounds are widespread in organic chemistry. Magnesium can react with haloalkanes to give Grignard reagents.
Examples of Grignard reagents are phenylmagnesium bromide and ethylmagnesium bromide.
Later, magnesium filament was used in electrically ignited single-use photography flashbulbs.

Magnesium powder is used in fireworks and marine flares where a brilliant white light is required.The metal is now obtained mainly by electrolysis of magnesium salts obtained from brine, and is used primarily as a component in aluminium-magnesium alloys, sometimes called magnalium or magnelium.Magnesium is less dense than aluminium, and the alloy is prized for its combination of lightness and strength.Magnesium is a chemical element with the symbol Mg and atomic number 12.It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure.Magnesium is the eleventh most abundant element by mass in the human body and is essential to all cells and some 300 enzymes.Magnesium ions interact with polyphosphate compounds such as ATP, DNA, and RNA.It is the third most abundant element dissolved in seawater, after sodium and chlorine.Magnesium occurs naturally only in combination with other elements, where it invariably has a 2 oxidation state.It tarnishes slightly when exposed to air, although, unlike the heavier alkaline earth metals, an oxygen-free environment is unnecessary for storage because magnesium is protected by a thin layer of oxide that is fairly impermeable and difficult to remove.Magnesium reacts with water at room temperature, though it reacts much more slowly than calcium, a similar group 2 metal.
