Iron (Fe, atomic number 26) is a redox-active transition metal element found in living systems as Fe2+ or Fe3+ ions. It is rarely found free in biology, but is bound to proteins such as ferritin ...

This means that the chemical formula used for a metal is simply the symbol for the element. For example, the formula for iron is Fe, even though a piece of iron contains very many iron atoms.

During the H 2 reduction, iron oxides were reduced to iron ... The left-end Pt atom anchored the C=C bond, while the central Fe atom activated the C=O bond, which was further hydrogenated by ...
