Iron is the 26th element in the periodic table according to its atomic number 26. It is a ferromagnetic substance which is strongly attracted by magnetic field. Its chemical symbol is Fe.
With some Carbon, Iron can be turned into steel, which helps strengthen it and prevents fractures. With approximately 11% Chromium, Iron can be transformed into Stainless Steel, which prevents rust.
