Magnesium Homework Help, Assignment Help, …

Magnesium is a white, lustrous metal which is fairly soft and ductile (e.g. magnesium ribbon), it tarnishes somewhat in moist air, a film of the oxide, MgO, being formed. On heating in air, magnesium burns with a brilliant light forming both the oxide and the nitride, MgN 2. These appear as a white smoke which can be deposited on a flat surface
