Who discovered the element 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.
Who discovered Element 113?
Kosuke Morita
Kosuke Morita, who led a group of researchers that discovered element 113, speaks at a press conference at in Tokyo on June 9. The name nihonium stems from the fact that element 113 was discovered in Japan, and Nihon is one way to say the country’s name in Japanese. It’s time to update your copy of the periodic table.
Where is the element niobium found?
Natural abundance The main source of this element is the mineral columbite. This mineral also contains tantalum and the two elements are mined together. Columbite is found in Canada, Brazil, Australia, Nigeria and elsewhere. Some niobium is also produced as a by-product of tin extraction.
When was niobium first used?
Niobium was officially adopted as the name of the element in 1949, but the name columbium remains in current use in metallurgy in the United States. It was not until the early 20th century that niobium was first used commercially….

Who discovered fluorine?
Henri Moissan
Fluorine/Discoverers
Ferdinand Frederic Henri Moissan, a French chemist, was the first to successfully isolate fluorine in 1886. He did this through the electrolysis of potassium fluoride (KF) and hydrofluoric acid (HF).
When was fluorine discovered?
1886
Fluorine/Discovered
Success. Moissan finally succeeded in his quest to isolate fluorine on 26 June 1886, when he observed the formation of a gas at the anode, which burst into flames when tested with silicon.
Who discovered Flerovium?

Flerovium/Discoverers
Despite several attempts to make element 114, it was only in 1998 that a team led by Yuri Oganessian and Vladimir Utyonkov at the Joint Institute for Nuclear Research (JINR) in Russia produced it by bombarding plutonium with calcium.

Who named niobium?
In 1844, Heinrich Rose, working with samples of columbite and tantalite, produced two new separate, but very similar, acids, which he named niobic acid and pelopic acid. He renamed the element niobium.
Why is niobium named niobium?
In 1844 a German chemist, Heinrich Rose, discovered what he considered to be a new element occurring along with tantalum and named it niobium after Niobe, the mythological goddess who was the daughter of Tantalus. After considerable controversy it was decided that columbium and niobium were the same element.
Who discovered fluorine 18?
The noble gases, or Group 18 (VIIIA), also known as the inert gases, generally do not react with other elements. Fluorine was discovered in 1886 by French chemist Henri Moissan (1852-1907). Moissan collected the gas by passing an electric current through one of its compounds, hydrogen fluoride (H 2 F 2 ).
How did the element niobium get its name?
Niobium was discovered in 1801 by Charles Hatchett. Initially, it was named Columbium (with symbol Cb) after Columbia; a state of United States. Later, due to confusion, it was considered another element, known as tantalum, and in 1846, German Chemist Heinrich Rose proposed that it was indeed a novel element and named it Niobium.
How is niobium produced in the British Museum?
Some niobium is also produced as a by-product of tin extraction. When examining minerals in the British Museum in 1801, Charles Hatchett was intrigued by a specimen labelled columbite.
Where are niobium and tantalum found on the periodic table?
Placing Niobe and her father Tantalus next to one another in the periodic table is no accident. Both niobium and tantalum are found together in the mineral columbite, a mixed oxide that also contains iron and manganese, and they have similar chemical and physical properties.
What kind of steel is niobium used for?
It is used in making high-grade structural steel. Niobium was discovered in 1801 by Charles Hatchett. Initially, it was named Columbium (with symbol Cb) after Columbia; a state of United States.
