Mg - Magnesium - periodic table of the elements

A flammable and light weight alkaline earth metal. Joseph Black discovered the element in 1755 in Scotland, and Davy produced the pure metal with his electrolytic apperatus in 1808. Industrially, magnesium is used extensively in lightweight alloys. Ions of magnesium are essential for most organisms. Usually coupled with Calcium in dietary supplements.
