<P> Iron is a chemical element with symbol Fe ( from Latin : ferrum ) and atomic number 26 . It is a metal in the first transition series . It is by mass the most common element on Earth , forming much of Earth 's outer and inner core . It is the fourth most common element in the Earth 's crust . Its abundance in rocky planets like Earth is due to its abundant production by fusion in high - mass stars , where it is the last element to be produced with release of energy before the violent collapse of a supernova , which scatters the iron into space . </P>
