CAS 7439-95-4PubChem CID 5462224

Magnesium

Magnesium appears as a light silvery metal. The more finely divided material reacts with water to liberate hydrogen, a flammable gas, though this reaction is not as vigorous as that of sodium or lithium with water. In finely divided forms is easily ignited. Burns with an intense white flame. Can be wax coated to render magnesium as nonreactive. — CAMEO Chemicals
