Iron (Fe) - Atomic Mass Number, Melting Point,

Iron – Heavy Metal. Iron is a chemical element in the periodic table that has the symbol Fe and atomic number 26. Iron is a group 6 and period 4 metal. Iron is notable for being the final element produced by stellar nucleosynthesis, and thus the heaviest element which does not require a supernova or similarly cataclysmic event for its formation.
