The element Magnesium got its name when it was discovered. It is a silvery white metal that is highly reactive. Its chemical symbol is Mg and atomic number is 12. Its atomic mass is relatively 24. That means it has 12 protons 12 neutrons and 12 electrons. According to Steve Gagnon in “The Element Magnesium” Magnesium was isolated by Sir Humphry Davy, an English chemist, through the electrolysis of a mixture of magnesium oxide and mercuric oxide in 1808.
Magnesium has a melting point of 650° C (1202° F), a boiling point of 1090° C (1994° F), a density of 1.74 g/ cm3 at 20° C (68° F), and a mean specific heat of 1.023 J g−1 K−1 (0.249 cal/ g × °C). Pure magnesium is highly active chemically and, therefore, does not occur free in nature, but
