Magnesium (IPA: /magˈnɪːziəm, -ʒəm/) is the chemical element in the periodic table that has the symbol Mg and atomic number 12 and an atomic mass of 24.31. Magnesium is the eighth most abundant element and constitutes about 2% of the Earth's crust by weight, and it is the third most plentiful element dissolved in seawater. Magnesium ion is essential to all living cells. The free element (metal) is not found in nature. Once produced from magnesium salts, this alkaline earth metal is primarily used as an alloying agent to make aluminium-magnesium alloys, sometimes called "magnalium" or "magnelium".

magnesium is a metallic element.
Mg is its chemical symbol.
Mg is an alkaline earth metal.
atomic number is 12.
atomic mass = 24.31
8th most abundant element in the earth's crust.
known isotopes are: magnesium-24, magnesium-25, and magnesium-26.
magnesium ion is usually Mg2+.

It's an elemental metal, sometimes used in alloys, and highly flammable in its purified state. Once it's burning water won't quench it - in fact, it will burn even hotter and brighter with a water source.
