Origin / Meaning of the name Tellurium
The name originates from the Greek word 'tellus' meaning Earth

Periodic Table Group and Classification of the of the Tellurium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Tellurium is classified as a "Metalloid" element and is located in Groups 13, 14,15, 16 and 17 of the Periodic Table. An element classified as one of the Metalloids has the properties of both metals and Non-Metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers.

Facts about the Discovery and History of the Tellurium Element
Tellurium was discovered by Franz-Joseph Muller von Reichenstein in 1782 in Romania. It was isolated by Martin Heinrich Klaproth in 1798.

What is Tellurium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day in his day but still all fitting into his concept of  the "Periodic Table" in which Tellurium is just one element that can be found.
