When was niobium discovered?
1801
Niobium/Discovered
Niobium was first discovered (1801) in an ore sample from Connecticut by the English chemist Charles Hatchett, who called the element columbium in honour of the country of its origin, Columbia being a synonym for the United States.
Why was niobium named after Niobe?
Niobium is named for the Greek goddess of tears, Niobe, who was the daughter of king Tantalus, according to the Royal Society of Chemistry, due to the element’s similarities to tantalum (named for the king). The estimated amount of niobium in the Earth’s crust is thought to last for the next five centuries.
Where is niobium found in the world?
The element is found in niobite (or columbite), niobite-tantalite, parochlore, and euxenite. Large deposits of niobium have been found associated with carbonatites (carbon-silicate rocks), as a constituent of parochlore. Extensive ore reserves are found in Canada, Brazil, Nigeria, Zaire, and in Russia.
Is niobium named after a scientist?
The German chemist Heinrich Rose determined in 1846 that tantalum ores contain a second element, which he named niobium….

Who discovered fluorine?
Henri Moissan
Fluorine/Discoverers
Henri Moissan, a French chemist, finally isolated fluorine in 1886 — after being poisoned several times in his pursuit. He was awarded the Nobel Prize in 1906 for the isolating fluorine by electrolysis of dry potassium hydrogen fluoride (KHF2) and dry hydrofluoric acid.

What food contains niobium?
Niobium can be found in a number of food items such as garlic, red beetroot, parsnip, and broccoli, which makes niobium a potential biomarker for the consumption of these food products. The English chemist Charles Hatchett reported a new element similar to tantalum in 1801 and named it columbium.
Where is niobium found in Canada?
A large deposit of niobium, a metal valuable for alloying steel, has been discovered in Canada by a group of companies headed by Imperial Oil, Ltd. The deposit is in the James Bay lowlands, 400 miles north of Toronto. It contains 40 million tons of crude pyrochlore ore—a complex of sodium, calcium, and niobium oxides.
Who named fluorine?
The nearly anhydrous acid was prepared in 1809, and two years later the French physicist André-Marie Ampère suggested that it was a compound of hydrogen with an unknown element, analogous to chlorine, for which he suggested the name fluorine.
Why was fluorine named?
The name fluorine is derived from the mineral fluorite which comes from the Latin word “fluere” meaning “to flow.” The name was suggested by English chemist Sir Humphry Davy.
