Province Of Valladolid
Valladolid () is a Provinces of Spain, province of northwest Spain, in the central part of the Autonomous communities of Spain, autonomous community of Castile-Leon, Castile and León. It has a population of 520,716 people in a total of 225 municipalities, an area of and a population density of 64.19 people per km2. The capital is the city of Valladolid. It is bordered by the provinces of Zamora (province), Zamora, León (province), León, Palencia (province), Palencia, Burgos (province), Burgos, Segovia (province), Segovia, Ávila (province), Ávila, and Salamanca (province), Salamanca. It is thus the only Spanish province surrounded entirely by other provinces of the same autonomous community. It is the only peninsular province which has no mountains. Because the extensive plain on which the province lies is strategically important to overland transport, it is a major communications hub. From a national point of view it connects Madrid with the north of Spain, from Vigo in Gali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...
