Airn is achemicalelement in the periodic cairt that haes the symbolFe (L.:Ferrum) an atomic nummer 26. Airn is a group 8 an period 4Metal. 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.
