The name was based on the wide range of colors found in vanadium compounds. Del Río's lead mineral was ultimately named vanadinite for its vanadium content. In 1867, Henry Enfield Roscoe obtained the pure element. Vanadium occurs naturally in about 65 minerals and fossil fuel deposits. It is produced in China and Russia from steel smelter slag.
Vanadium (named after Vanadís, another name for Freyja, the Scandinavian goddess of fertility) was originally discovered by Andrés Manuel del Río (a Spanish-born Mexican mineralogist) in Mexico City in 1801. He discovered the element after being sent a sample of "brown lead" ore (plomo pardo de Zimapán, now named vanadinite).
This list of chemical elements named after people includes elements named for people both directly and indirectly. Of the 118 elements, 19 are connected with the names of 20 people. 15 elements were named to honor 16 scientists (as curium honours both Marie and Pierre Curie). Four others have indirect connection to the names of non-scientists. [1]
Nils Gabriel Sefström (2 June 1787 – 30 November 1845) was a Swedish chemist.Sefström was a student of Berzelius and, when studying the brittleness of steel in 1830, he rediscovered a new chemical element, to which he gave the name vanadium.
The popular workout Pilates is also named after its inventor. Even some more frightening items, including guillotines and one specific type of rifle, carry their creator's name as their own.
Nils Gabriel Sefström rediscovered the element in 1830 and named it vanadium. Friedrich Wöhler then showed that vanadium was identical to erythronium and thus that del Río had been right in the first place. [108] [109] Del Río then argued passionately that his old claim be recognised, but the element kept the name vanadium. [109] 41 Niobium ...
This is a list of scientific units named after people.For other lists of eponyms (names derived from people) see eponym.By convention, the name of the unit is properly written starting with a lowercase letter (except where any word would be capitalized), but the first letter of its symbol is a capital letter if it is derived from a proper name.
It turns out that the vast majority of brands named after real people are — of course — named after the company's founder. But each of these founders has a unique and oftentimes fascinating story.
