Hi. Karen.
No, Mg won't burst into flames when placed in water but it will burn under
water. You must first start it burning with an external source of high heat,
most generally a very hot flame of some sort. In aircraft it was usually
the gasoline, or maybe oil, that burned first, setting the metal on fire.
Welding of Magnesium used to be extremely difficult because of the fire
hazard. But today, inert gas welding mekes it much easier.
In the early years of photography, it was powdered magnesium that was used
the make the flash for the photographic work. I think we have all seen a
movie or two where there was the big Whoosh of the flash of the cameraman.
That was burning magnesium powder. Powdered aluminum will do the same, but
not quite so fast or with as much bright light.
It is pure Sodium (Na) that is so active that when placed in water it will
erupt into flame. It splits from each other the O and H atoms which make up
the H2O molecule of water. The chemical reaction is so violent that heat and
light are produced. I don't remember the exact chemical equation but the
result is a refusion of the Na, H, and O into Sodium Hydroxide( NaOH2 -
metallic salt - corrosive) soluble in water, and some free hydrogen, which,
due to the intense heat immediately recombines with free O2 to produce water
droplets.
As I recall it had to be stored in a container filled with oil...........or
was that phosphorus? Hmmmm. Now I have to get out my dusty old Chemisty 101
book and refresh my memory.
OK. Enough. Probably more that you wanted or needed anyway, right? lol!!
Have a good day.
John

John - about that Mg fire - sorry we asked!! But very interesting. Is it a
Mg substance that can be dropped into a puddle causing the puddle to whoosh
into flames? Karen Gringhuis

John et. al.,
Your correct both Phosphorous and Sodium must be stored under oil.
Calcium also reacts violently with water.
