élément niobium.
Nb (Niobium) is an element with position number 41 in the periodic table. Located in the V period. Melting point: 2468 ℃. Density: 8.58 g/cm 3 . The order of filling the orbitals with electrons in the Nb atom is an exception to the rule. Expected electronic configuration. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d3.
The story of niobium's discovery is a bit confusing. The first governor of Connecticut, John Winthrop the Younger, discovered a new mineral around 1734. He named the mineral columbite ((Fe, Mn, Mg)(Nb, Ta) 2 O 6) and sent a sample of it to the British Museum in London, England. The columbite sat in the museum's mineral collection for years ...
The element . Niobium was discovered by C. Hatchett in year 1801 in United Kingdom.. Niobium was first isolated by W. Blomstrand in 1864.Niobium derived its name from Niobe, daughter of king Tantalus from Greek mythology.Hatchett found the element incolumbiteore and named it columbium. Heinrich Rose proved in 1844 that the element is distinct from …
Niobium [ˈnioːp] (after Niobe, the daughter of tantalum) is a chemical element with the element symbol Nb and the atomic number 41. It is one of the transition metals, in the periodic table it is in the 5th period and the 5th subgroup (group 5) or vanadium group. In the Anglo-Saxon language area is still today many metallurgists, material ...
Niobium's toughness, resistance to corrosion and excessive melting point makes it a great alloy to steel that's applied when sturdiness is essential. It's why around 75 percent of this mineral is used as an alloy in high-energy steel found in pipelines, transportation, and structural applications. Niobium's impressive resistance to heat ...
Niobium, previously known in the U.S. as columbium, is a chemical element under the symbol Nb with the atomic number 41. Niobium is a soft, whitish, ductile, transition metal often found in the minerals pyrochlore and columbite. The name niobium comes from Greek mythology. Niobe is the daughter of Tantalus, after whom tantalum is …
niobium. 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 ...
Major end-use distribution of reported niobium consumption was as follows: steels, 74%; and superalloys, 26%. In 2009, the estimated value of niobium consumption was $162 million and was expected to be about $330 million in 2010, as measured by the value of imports. Recycling: Niobium was recycled when niobium-bearing steels and superalloys ...
Niobium Slogan. Niobium, Hear It Roar! It's An Element Not to Ignore. Just ask NASA, I implore. Niobium. It's shiny and that's all that matters! Atomic number 41, Niobium is lots of fun. Niobium: Learn about this element so you wont end up like a nio"bum". Niobium: It's shiny, it's gray, and when it's cool… its a SUPERCONDUCTOR!
