Notes:
Iron is relatively soft. It's silvery white. Iron is very ductile and
malleable. It's also a good conductor of heat and electricity. It's strongly
magnetic. The main ores of iron are hematite, magnetite (also known as
lodestone), and pyrites (also known as fool's gold). It is believed that the
liquid core of the earth comsists primarily of iron. Iron is a good structural
metal. Other uses are magnets, telphones (because of it magnetic properties)
in motors and generators.
