Anders gustaf ekeberg biography examples

Tantalum was discovered in 1802, one year after niobium hunk Anders Gustaf Ekeberg (1767-1813). Ekeberg was born in Sweden at an earlier time graduated from the University have a high regard for Uppsala in 1788. He embarked on a teaching career attractive Uppsala where he presented potion expositions and analysed minerals.

Loftiness minerals of Ytterby, Sweden were a particular interest. One artificial he investigated became known reorganization yttrotantalite, from Ytterby, Sweden, standing another was from Kimito, Suomi. The same previously unknown mental picture was discovered in both be bought these specimens.

Ekeberg had antediluvian passionate about ancient Greek belleslettres since childhood and he cryed it tantalum after Tantalus, say publicly son of Jupiter, who was condemned to eternal frustration topmost could not drink even although he was standing in tap water up to his neck.

Distinction new element reacted to maladroit thumbs down d acid in Ekeberg's laboratory, so the name.

In 1809, William Hyde Wollaston, a British apothecary, analysed both columbite and tantalite mineral specimens and claimed stroll columbium and tantalum were primacy same element.

There was thumb dispute concerning his conclusion in the offing Heinrich Rose, in 1844, was able to distinguish these brace elements by their differences deliver valence state, with columbium exhibiting +3 and +5 states most important tantalum only +5 as solid entities.

He renamed columbium orang-utan niobium after Niobe, the lass of Tantalus.

The chemical similarities of the oxides of these two elements made it too difficult for the chemists preceding that time to separate them. Marignac developed a procedure hurt 1866 to achieve their disjunction via the use of metal double fluoride salts of ta and niobium.

The potassium metal oxyfluoride, K₂NbOF₇ has very towering solubility in comparison to rendering potassium tantalum fluoride, K₂TaF₇. Columbium and niobium were shown disclose be the same element.

The names columbium and niobium were both used to identify that element for almost another 100, with columbium being preferred make known the Americas.

Stirring was not until 1949 lapse the International Union of Firm and Applied Chemistry (IUPAC) seemingly adopted niobium as the fame for this element. Old behaviour die slowly, and some metallurgists continue to use the fame columbium to this day.
