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.
Andrés Manuel del Río y Fernández (10 November 1764 – 23 March 1849) was a Spanish scientist, naturalist and engineer who discovered compounds of vanadium in 1801. He proposed that the element be given the name panchromium, or later, erythronium, but his discovery was not credited at the time, and his names were not used.
The concentration of vanadium in the blood of ascidian tunicates is as much as ten million times higher [specify] [102] [103] than the surrounding seawater, which normally contains 1 to 2 μg/L. [104] [105] The function of this vanadium concentration system and these vanadium-bearing proteins is still unknown, but the vanadocytes are later ...
Prepared and isolated from urine, it was the first element whose discovery date and discoverer are recorded. [53] Its name first appears in print in the work of Georg Kaspar Kirchmayer in 1676. Recognised as an element by Lavoisier. [1] 1 Hydrogen: 1671 R. Boyle: 1671 R. Boyle Robert Boyle produced it by reacting iron filings with dilute acid.
Donnel Foster Hewett (June 24, 1881, Irwin, Pennsylvania – February 5, 1971) was an American geologist and mineralogist, known for his leading role in the 1905 discovery of the Minas Ragra vanadium ore deposit in Peru. [1] This ore deposit was the world's principal source of vanadium for more than 30 years.
Vanadium is a trace metal that is relatively abundant in the Earth (~100 part per million in the upper crust). [1] Vanadium is mobilized from minerals through weathering and transported to the ocean. Vanadium can enter the atmosphere through wind erosion and volcanic emissions [1] and will remain there until it is removed by precipitation. [1]

In 1845, Rose published the discovery of a new element pelopium, which he had found in the mineral tantalite. [11] After subsequent research, pelopium was identified to be a mixture of tantalum and niobium. [12] In 1830, Heinrich Rose was elected a foreign member of the Royal Swedish Academy of Sciences.
