What type of metal is vanadium?
vanadium (V), chemical element, silvery white soft metal of Group 5 (Vb) of the periodic table. It is alloyed with steel and iron for high-speed tool steel, high-strength low-alloy steel, and wear-resistant cast iron.
Who discovered vanadium pentoxide?
In 1801, the Spanish mineralogist, Andrés Manuel Del Rio, discovered an element with the atomic number 23, in Mexico, in a lead mineral. Due to the similarity of its colors to those of chrome, Del Rio called this element as panchrome.
How was vanadium discovered?
Vanadium was discovered in 1801 by the Spanish mineralogist Andrés Manuel del Río. Del Río extracted the element from a sample of Mexican “brown lead” ore, later named vanadinite. He found that its salts exhibit a wide variety of colors, and as a result he named the element panchromium (Greek: παγχρώμιο “all colors”).
What type of metal is niobium?
transition metal
Niobium, also known as columbium, is a chemical element with the symbol Nb (formerly Cb) and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal. Pure niobium has a Mohs hardness rating similar to that of pure titanium, and it has similar ductility to iron.
Is niobium a metal?
Niobium is a rare, soft, malleable, ductile, gray-white metal. It has a body-centered cubic crystalline structure and in its physical and chemical properties it resembles tantalum.
Who discovered chromium?
Louis Nicolas Vauquelin
Chromium/Discoverers
Chromium was discovered (1797) by the French chemist Nicolas-Louis Vauquelin and isolated as the metal a year later; it was named for its multicoloured compounds.
What is the metal vanadium used for?
Vanadium can be used to make steel alloys, for use in space vehicles, nuclear reactors and aircraft carriers, etc. Vanadium steel alloys’ strength means that they are perfectly suited to the creation of tools, axels, piston rods and as girders in construction. Vanadium can be utilised in ceramics as a pigment.
Who discovered niobium?
Charles Hatchett
Niobium/Discoverers
Niobium was the first of these two elements to be discovered. In 1801, Charles Hatchett (1765-1847), an English chemist, analysed a specimen of an unknown mineral from the collection of the British Museum in London.
