Klaproth discovered uranium (1789) [6] and zirconium (1789). He was also involved in the discovery or co-discovery of titanium (1795), strontium (1793), cerium (1803), and chromium (1797) and confirmed the previous discoveries of tellurium (1798) and beryllium (1798). [7] [8] Klaproth was a member and director of the Berlin Academy of Sciences. [2]
Tellurium is a chemical element; it has symbol Te and atomic number 52. ... In 1896, that tailing was discovered to be calaverite, a telluride of gold, ...
Even articles by Mary Elvira Weeks on the discovery of tellurium, published in the Journal of Chemical Education in 1932, [5] and 1935 [6] quote two different locations of his birth: one in Vienna, Archduchy of Austria and the other Hermannstadt, Principality of Transylvania (present-day Sibiu, Romania). A newer biography on the topic makes ...
Oxygen was discovered by Joseph Priestley in 1774 when he focused sunlight on a sample of mercuric oxide and collected the resulting gas. Carl Wilhelm Scheele had also created oxygen in 1771 by the same method, but Scheele did not publish his results until 1777. [2] Tellurium was first discovered in 1783 by Franz Joseph Müller von Reichenstein ...
As well as studying the flora and hydrography of Hungary, in 1789 he discovered the element tellurium, but later gave the credit to Franz-Joseph Müller von Reichenstein (1740–1825) who had actually discovered it in 1782.
The chemical elements were discovered in identified minerals and with the help of the identified elements the mineral crystal structure could be described. One milestone was the discovery of the geometrical law of crystallization by René Just Haüy , a further development of the work by Nicolas Steno and Jean-Baptiste L. Romé de l'Isle (the ...
Using this material he later discovered tellurium sulfoxide and developed a new method for the quantitative separation of tellurium from selenium. These and other papers on tellurium and selenium were published in the Journal of the Chemical Society during 1883–1885. There he published more than 20 other paper within a short period of 1884 ...
Calaverite, or gold telluride, is an uncommon telluride of gold, a metallic mineral with the chemical formula AuTe 2, with approximately 3% of the gold replaced by silver.It was first discovered in Calaveras County, California in 1861, and was named for the county in 1868.
