Element Story - Tellurium

Tellurium is an element with atomic number 52, belonging to Group 16 in the periodic table. It's a brittle, silvery-white metalloid with a metallic luster, and its electrical conductivity changes with temperature and light. Naturally, it's found in small amounts mainly in sulfide ores of copper and lead, and is often obtained as a byproduct during the refining of these metals. When alloyed with other metals, tellurium can enhance workability and durability, making it useful in special alloys and steel manufacturing. Cadmium telluride (CdTe) is used as an absorber layer material in solar cells, and bismuth telluride is used in thermoelectric devices to convert temperature differences into electrical energy. Tellurium is not an essential element for life, and some of its compounds can be toxic. In the universe, tellurium is formed through processes like stellar nucleosynthesis and supernova explosions. Its isotopes provide important clues for studying the creation of elements heavier than iron and the distribution of elements in the cosmos.
