How many valence electrons does niobium have

Allotropes Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties. For more information on the Visual Elements image see the Uses and properties section below. Group A vertical column in the periodic table.

Niobium is a chemical element ; it has symbol Nb formerly columbium , Cb and atomic number It is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to pure titanium , [5] and it has similar ductility to iron. Niobium oxidizes in Earth's atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel. Niobium is often found in the minerals pyrochlore and columbite , hence the former name "columbium".

Niobium is often found in the minerals pyrochlore and columbite , hence the former name "columbium". Its name comes from Greek mythology : Niobe , daughter of Tantalus , the namesake of tantalum. The name reflects the great similarity between the two elements in their physical and chemical properties, which makes them difficult to distinguish.

Niobium pronounced as ni-OH-bee-um belongs to the family of transition metals, denoted by the chemical symbol Nb. Defined as a soft and ductile metal with eighteen isotopes, it is available in the form of foil, sheet, tube, rod, and powder. When exposed to air oxygen at room temperature, it develops a bluish tint [1, 2, 11]. The metal is found associated with carbonatites in pyrochlore while its ore deposits have been discovered in the mining regions of Brazil, Canada, Russia, Zaire, and Nigeria who are also its major producers [11]. It is named after Niobe, the daughter of King Tantalus in Greek mythology, who was turned into a stone while crying after the murder of his fourteen children [1]. Its actual year of discovery goes back to when John Winthrop, the first governor of Massachusetts Bay Colony and an avid mineral collector, found a new mineral that was sent to the British Museum and named it columbite. A new twist in the discovery of niobium took place in when the English chemist and physicist William Hyde Wollaston compared the mineral with another mineral called tantalite and announced that columbium was actually the element tantalum. Another confusion related to its finding arose in when Heinrich Rose, a German mineralogist, and chemist, used samples of columbite and tantalite to produce two new acids, niobic and pelopic that were believed to be similar to each other. It was resolved after twenty-two years by a Swiss Chemist called Jean Charles Galissard de Marignac who proved that the newly isolated acids were from two different elements.

Niobium also has the other name as Columbium due to its source of extraction. The element was christened after Niobe, the daughter of Tantalus in Greek mythology. Retrieved 15 July Atomic number. Electron configuration Shorthand configuration. We welcome your feedback. The Aldrich Catalogue of Fine Chemicals still has Columbium as an explanatory subheading for any confused Americans out there. Archived from the original on 2 April It is also readily prone to hydrolysis and is barely soluble in dilute solutions of hydrochloric , sulfuric , nitric and phosphoric acids due to the precipitation of hydrous Nb oxide. Several methods are used for the reduction to metallic niobium.

The RSC maintains this Site for your information, education, communication, and personal entertainment. The oxidation state of an atom is a measure of the degree of oxidation of an atom. This was chosen because of niobium's chemical similarity to tantalum Allotropes. Frequently after more spectacular chemistry demonstrations, the scientist on stage will warn the audience 'not to try this at home'. The most stable of niobium's isomers is 93m Nb with half-life With this method, a relatively high purity niobium can be obtained.
