Iron (Fe) Element Properties
Atomic Mass 55.847
Atomic Number 26
Name Origins Anglo-Saxon, iron; Latin, ferrum.
Year Discovered Prehistoric.
Discovery Credits Known to ancient civilizations.
Remarks When pure, iron is lustrous, and soft (workable). Most important of all metals, used principally as steel alloys. Rusts in damp air, dissolves in dilute acids.

Diagnostic tests: 
The borax bead test in the oxidizing flame gives yellow to brownish red color while hot and is colorless to yellow when cold. Reducing flame gives a bottle green color.
A magnetic mass is obtained if the mineral is powdered, mixed with soda (Na2CO3), and fused in a reducing flame (Note, cobalt and nickel also yield magnetic masses).
In solution, iron will precipitate as Fe(OH)3 when excess amounts of NH4OH are added.
