Description
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 ninth most abundant element in the universe. [9][10] It is produced in large, aging stars from the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas, much of the magnesium is expelled into the interstellar medium where it may recycle into new star systems.
Properties
The solid, silvery-shiny light metal magnesium belongs to alkaline earth metals. It is relatively resistant to hydrofluoric acid and alkalis, in contrast to aluminum.

Application
Often, magnesium rods act as sacrificial anodes, protecting parts of more noble metals from corrosion . In motor vehicles, magnesium alloys were used for the manufacture of housing parts as well as to produce rims for large vehicles.
