Magnesium
Information
Atom name: Magnesium (Mg)
Atomic mass: 24.305 (24)
Atomic Number: 12
The electrons are arranged around the nucleus in a 2-8-2 pattern. It has two valence electrons which makes it less reactive than sodium (1 valence electron), but more reactive than aluminum (3 valence electrons).
Magnesium is a highly flammable element discovered by John Black in 1755 in England. It was isolated by Sir Humphry Davy in 1808. Magnesium is both strong and lightweight. When used to build things such as cars and airplanes, it is often mixed with other metals. It is often used in fireworks and flares due to its extraordinarily bright light when burnt. Unlike most flame, a fire started with magnesium will actually worsen when water is thrown on it.
