Vanadium
is mainly used to produce specialty steel alloys such as high speed tool steels . The compound vanadium pentoxide is used as a catalyst for the production of sulfuric acid . Vanadium is found in many organisms, and is used by some life forms as an active center of enzymes. Contents
List of chemical elements naming controversies
In 1831, Sefström of Sweden rediscovered vanadium in a new oxide he found while working with some iron ores and named the element accordingly vanadium ; later that same year Friedrich Wöhler confirmed del Río's earlier work. [ 2 ] Later, George William Featherstonhaugh , one of the
Yttrium
In 1787, Carl Axel Arrhenius found a new mineral near Ytterby in Sweden and named it ytterbite , after the village. Johan Gadolin discovered yttrium's oxide in Arrhenius' sample in 1789, [ 3 ] and Anders Gustaf Ekeberg named the new oxide yttria . Elemental yttrium was first isolated in

Anti-diabetic drug
Several groups of drugs, mostly given by mouth, are effective in Type II, often in combination. The therapeutic combination in Type II may include insulin, not necessarily because oral agents have failed completely, but in search of a desired combination of effects. The great advantage of injected
Panchromium
element. [ 1 ] [ 2 ] In 1831 Nils Gabriel Sefström rediscovered the element and called the element vanadium . In 1831, the geologist George William Featherstonhaugh suggested that vanadium should be renamed " rionium " after del Río, but this suggestion was not followed. [ 3 ] [ edit
Iron
Iron is the most common element in the earth as a whole, and the fourth most common in the Earth's crust. It is produced as a result of stellar fusion in high-mass stars, and it is the heaviest stable element produced by stellar fusion because the fusion of iron is the last nuclear fusion reaction
Chromium
Chromium was regarded with great interest because of its high corrosion resistance and hardness. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding chromium to form stainless steel . This application, along with chrome plating
Nils Gabriel Sefström
Andrés Manuel del Río in 1801. He named it erythronium. Friedrich Wöhler later confirmed that vanadium and erythronium were the same substance. [ 2 ] Sefström was member of the Royal Swedish Academy of Sciences from 1815. [ edit ] References ^ N. G. Sefström (1831). "Ueber das
Molybdenum
Molybdenum minerals have long been known, but the element was "discovered" (in the sense of differentiating it as a new entity from minerals salts of other metals) in 1778 by Carl Wilhelm Scheele . The metal was first isolated in 1781 by Peter Jacob Hjelm . Most molybdenum compounds have low
