why does magnesium burn so hard, fast and hot ?

Great question Mathew -
Atoms have a positive nucleus with just
enough negative electrons "roaming " around it to just balance the
charge. Oxygens in the air have a strong affinity for extra electrons
and magnesium atoms can readily give up electrons. The reaction gives
Mg2+ ions and O2- ions which are strongly attracted to each other to
form MgO, thus giving off lots of energy.

Why can't you use water or a fire extinguisher to extinguish a magnesium fire?
