Rose then suggested the name niobium for the new element. The name comes from Greek mythology. Niobe is the daughter of the god Tantalus, from whom the name tantalum comes. Scientists debated for nearly a century over which name to use. In 1949, niobium was officially adopted. However, many metallurgists (scientists who work with metals) …

The chemical element niobium (Nb) is a soft, malleable metal of Group 5 (Vb) of the periodic table. In 1801 the English chemist Charles Hatchett discovered a metal and named it columbium. Some 40 years later another chemist, Heinrich Rose of Germany, rediscovered the metal and named it niobium. Ever since, despite an international …

niobium, Metallic chemical element, chemical symbol Nb, atomic number 41. Often found in conjunction with tantalum, it was named after Niobe, the daughter of Tantalus in Greek mythology. The pure metal is soft and ductile; it looks like steel or, when polished, like platinum. It has excellent corrosion resistance.

Metallic niobium was finally isolated by the Swedish chemist Christian Wilhelm Blomstrand in 1864. Today, niobium is primarily obtained from the minerals columbite and pyrochlore ((Ca, Na) 2 Nb 2 O 6 (O, OH, F)). Niobium is used as an alloying agent and for jewelry, but perhaps its most interesting applications are in the field of ...

In many places niobium is known as columbium since it was originally "discovered" in a mineral named columbite. However, careful subsequent analysis indicated that the "new" element was actually Tantalum. The rediscovery of the element we know now as niobium was not even associated with columbium until after the official statistics were in.

Niobium is a chemical element with atomic number 41 in the periodic table. It's the most plentiful metal found in Earth's crust. Being a member of the transition metals family of periodic table elements, this superconductor can have 2, 3, or 5 electrons in the outermost valence shell that play a part in the chemical bonds of niobium with the other elements.

He named the element columbium (symbol Cb). In 1846 German chemist Henrich Rose independently discovered the element and named it niobium. The metal was first isolated by Swedish scientist Christian Blomstrand in 1864. He reduced the chloride by heating it in a hydrogen atmosphere. The name niobium was adopted internationally in 1950.
