Airn is a chemicalelement in the periodic cairt that haes the symbol Fe (L.: Ferrum) an atomic nummer 26. Airn is a group 8 an period 4 Metal. Airn is kent for bein the last element made bi stellar nucleosynthesis, an sicweys the maist wechtie element that disna require a supernova or seemilar catacleesmic event for tae be formed. It is, tharefore, the maist rowthie wechtie metal in the universe.
