What are some cool facts about magnesium?
Magnesium is a silvery-white alkaline earth metal. Magnesium is named for the Greek city of Magnesia, a source of calcium oxide, which is called magnesia. Magnesium is the ninth-most abundant element in the universe. Magnesium forms in large stars as a result of the fusion of helium with neon.
What is magnesium 12 used for?
Magnesium oxide (MgO), also known as magnesia, is the second most abundant compound in the earth’s crust. Magnesium oxide is used in some antacids, in making crucibles and insulating materials, in refining some metals from their ores and in some types of cements.

Magnesium/Discoverers
A pure, but tiny, amount of the metal was isolated in 1808 by Humphry Davy by the electrolysis of magnesium oxide. However, it was the French scientist, Antoine-Alexandre-Brutus Bussy who made a sizeable amount of the metal in 1831 by reacting magnesium chloride with potassium, and he then studied its properties.
