State of the Art in Computer Graphicsmetal has been of commercial importance only during the last two or three decades. Although it has some very desirable physical properties as an engineering metal, the high cost of production of the pure metal (Kroll process, chapter 10) still hinders its utilisation. It is used in supersonic aircra

It was because of the beauty of these colours that Sefstrom in 1830 named the element vanadium in honour

The maximum oxidation state +7 is shown in the permanganates, and all oxidation states from +7 to −3 are known; this is the widest range shown by a first-row transition element. Pure manganese is largely produced by electrolysis from aqueous solutions containing mangan

Collaboration on Digital Media, common. Iron has a very ancient history; it was probably first used by man nearly 6000 years ago (iron from meteorites), iron production beginning around 1200 B.C. Iron is the first member of the group VIII triad, lying above ruthenium and osmium. Unlike all the elements we have so far considered,

It occurs biologically in vitamin B., which contains Co. bonded octahedrally to five nitrogen atoms (four from pyrroline rings and one from a benzimidazole ring) and the carbon atom of a CN. group.

The number of possible co-ordination compounds in chemistry is almost infinite. Present-day res

Lewis Acids and Bases,simple’ substances will react with ligands? One way of dealing with this problem is to use the theory of acids and bases put forward by G.N. Lewis in 1938. Lewis called those substances capable of acting as ligands . and the substances with which these react .. The formal definitions may be summaris
