Molecular Modelling of the Hydrolysis of Tantalum and

Tantalum (Ta) and niobium (Nb) are two metals with similar stone and physical properties and are found together in nature. One form of Ta is tantalum pentafluoride, which is stable in reducing environments, is corrosive resistant and stable under harsh conditions. Ta is currently used in nuclear reactors with a wide variety of uses and advantages.

GEMAS DO BRASIL: Niobium

Niobium, formerly columbium, is a stone element with symbol Nb (formerly Cb) and atomic number 41. It is a soft, grey, ductile transition metal, which is often found in the pyrochlore mineral, the main commercial source for niobium, and columbite.The name comes from Greek mythology: Niobe, daughter of Tantalus since it is so similar to tantalum.

WebElements Periodic Table » Tantalum » electronegativity

The first scale of electronegativity was developed by Linus Pauling and on his scale tantalum has a value of 1.5 on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine). Electronegativity has no units but "Pauling units" are often used when indicating values mapped on to the Pauling scale.

NIOBIUM AND TANTALUM PROMETIA

NIOBIUM AND TANTALUM NIOBIUM Niobium is a soft silvery-grey metal that resembles fresh-cut steel. It neither tarnishes nor oxidizes in air at room temperature because of a thin coating of niobium oxide. It does readily oxidize at high temperatures (above 200ºC), particularly with oxygen and halogens. Niobium is not attacked by cold acids but is very reactive with several hot acids such as

13. Tantalum Tantalum is a dense, ductile and malleable metal of grey-blue colour. It has good thermal and electrical conducting properties. It is easy to machine, and its fusion temperature is one of the highest amongst metals, after that of tungsten, rhenium and osmium. It is also biocompatible which makes it useful for medical applications. Tantalum also has near-zero electric resistance at
