In recognition of this discovery in 1789, Klaproth named a new metal he had discovered after this element, uranium. Rather strangely, this was not the first sample of tellurium to pass through his hands. For a start, like many space monsters, it comes from slime; to be precise it is extracted from anode slime, a waste product formed during the electrolytic refining of copper.

Tellurium burns in air to form the dioxide tellurium(IV) oxide, TeO 2. It is also found uncombined in nature, but only very rarely. This name comes from the Greek word for "bronze ore," chalkos. Altogether then there were seven such heavenly bodies and seven was a magical number. The temperature at which the liquid–gas phase change occurs. Members of a group typically have similar properties and electron configurations in their outer shell. Isotopes The first two elements in the family, oxygen and sulfur, are often found in such ores. Covalent radiusHalf of the distance between two atoms within a single covalent bond. The higher the value, the larger risk there is to supply. So in 1798, when Klaproth had the chance to name another element, he named it after the only then known planet in the Solar System that did not have an element named after it, the Earth. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Costs Tellurium costs about $100/lb, with a purity of about 99.5%. Each planet was thought to have a particular influence on one metal or its ores. It burns in air with a greenish-blue flame and forms tellurium dioxide (TeO 2). Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced. Discovered by Muller von Reichenstein in 1782; named by Klaproth, who isolated it in 1798. It is also found uncombined in nature, but only very rarely. It is obtained commercially from the anode muds produced during the electrolytic refining of copper. Group Melting point The arrangements of electrons above the last (closed shell) noble gas. Tellurium is doped with gold and copper in semiconductor applications. Early man also knew of just seven metals, gold, silver, copper, iron, tin, lead and mercury; surely this could be no coincidence. The mass of an atom relative to that of carbon-12. Tellurium is a chemical element in the periodic table that has the symbol Te and atomic number 52. Visit my page about element collecting for a general description, or see photographs of all the samples from the set in a periodic table layout or with bigger pictures in numerical order. A measure of how difficult it is to compress a substance. The sum of the oxidation states within a compound or ion must equal the overall charge.
