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]
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 ...
Tellurium is a chemical element that has the symbol Te and atomic number 52. A brittle, mildly toxic, rare, silver-white metalloid which looks similar to tin, tellurium is chemically related to selenium and sulfur. It is occasionally found in native form, as elemental crystals. Tellurium is far more common in the universe than on Earth.
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.
