Tellurium: A Silent Guardian for the Elements
Tellurium is a chemical element with symbol Te and atomic number 52. This element is rarely found on Earth, yet it’s essential for life on the planet. It’s found in over 200 different minerals which are essential for human, animal, and plant life.
History and Discovery of Tellurium
Tellurium time spans along with human civilization, yet it wasn’t until 1798 when Martin Klaproth, a German chemist, isolated it. Klaproth was studying samples of ore that contained gold when he was surprised to discover a new element in it. People thought that he was crazy because he was the first to believe that an element could be found in the ore.
Klaproth named it tellurium, which is derived from the Latin word Tellus meaning Earth. His research was confirmed by another scientist named Johann Wobser in 1817. Interestingly, they both named the element Tellurium after the same Latin word “Tellus”.
