In chemistry, iron(II) refers to the element iron in its +2 oxidation state. In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) denoted by Fe . The adjective ferrous or the prefix ferro- is often used to specify such compounds — as in "ferrous chloride" for iron(II) chloride, FeCl2. … See more All known forms of life require iron. Many proteins in living beings contain bound iron ions; those are an important subclass of the metalloproteins. Examples include hemoglobin, ferredoxin, and the cytochromes See more Many iron(II) salts are soluble in water, such as iron(II) chloride FeCl2 and iron(II) sulfate FeSO4. Unlike their iron(III) counterparts, these … See more Iron(II) is a d center, meaning that the atom has six "valence" electrons in the 3d orbital shell. The 3d, 4s and 4p valence orbitals can therefore accept at most 12 electrons from a great variety of ligands to form coordination complexes and organometallic … See more WebIron(II) compounds. Compounds in the +2 oxidation state are weak reducing agents. They are normally light colored. They react with oxygen in air. They are also known as ferrous compounds.
