Metallic bond, force that holds atoms together in a metallic substance. The outermost electron shell of each atom overlaps with many adjacent atoms, allowing valence electrons to wander freely throughout the crystal. This accounts for many characteristic properties of metals: conductivity, malleability, and ductility.

Iron oxides produced during the process can be collected and reduced back to metallic iron using H 2, in a circular process where it becomes an energy carrier. Using clean energy in the recycling process enables storage and distribution of excess generated in periods of abundance. This concept uses and scales up existing dry metal cycle ...
The use of Fe 0 as sole electron donor has been reported for the first time in 2004 with the discovery of a novel bacterial strain that induced iron corrosion (oxidation) faster than hydrogen consuming microbes (Dinh et al., 2004).The uptake of electrons from metallic iron involves direct contact with the metal surface and may proceed through outer …
Left: Iron is easy to hammer into new shapes because its atoms are arranged in neat rows that can slip past one another. Right: Stainless steel (an alloy of iron) is much harder because small carbon atoms (red) in the "interstitial" spaces stop the iron atoms from moving. It also contains chromium (yellow) and other atoms (green).
EDTA removal from solutions using metallic iron was carried out at different values of pH, iron load and concentrations at free access of air and in closed vessels. The EDTA destruction was investigated using chemical and capillary electrophoresis analysis. Fe corrosion was studied voltammetrically and the composition …
