Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jujuy Province
Jujuy is a province of Argentina, located in the extreme northwest of the country, at the borders with Chile and Bolivia. The only neighboring Argentine province is Salta to the east and south. Geography There are three main areas in Jujuy: *The Altiplano, a plateau high with peaks of , covers most of the province. *The Río Grande of Jujuy cuts through the Quebrada de Humahuaca canyon, of heights between . *To the southeast, the sierras descends to the Gran Chaco region. The vast difference in height and climate produces desert areas such as the Salinas Grandes salt mines and subtropical Yungas jungle. The terrain of the province is mainly arid and semi-desertic across the different areas, except for the ''El Ramal'' valley of the San Francisco River. Temperature difference between day and night is wider in higher lands, and precipitation is scarce outside the temperate area of the San Francisco River. The Grande River and the San Francisco River flow to the Bermejo River. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India.

The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain.

Hall Valley
In architecture, a hall is a relatively large space enclosed by a roof and walls. In the Iron Age and early Middle Ages in northern Europe, a mead hall was where a lord and his retainers ate and also slept. Later in the Middle Ages, the great hall was the largest room in castles and large houses, and where the servants usually slept. As more complex house plans developed, the hall remained a large room for dancing and large feasts, often still with servants sleeping there. It was usually immediately inside the main door. In modern British houses, an entrance hall next to the front door remains an indispensable feature, even if it is essentially merely a corridor. Today, the (entrance) hall of a house is the space next to the front door or vestibule leading to the rooms directly and/or indirectly. Where the hall inside the front door of a house is elongated, it may be called a passage, corridor (from Spanish ''corredor'' used in El Escorial and 100 years later in Castl ...

North Tyrol
North Tyrol, rarely North Tirol (german: Nordtirol), is the main part of the Austrian state of Tyrol, located in the western part of the country. The other part of the state is East Tyrol, which also belongs to Austria, but does not share a border with North Tyrol. Besides those two regions, the historical region of Tyrol for many centuries also included the South Tyrol and the historical region of Welschtirol, which were annexed by Italy after World War I. With that, North Tyrol and East Tyrol were effectively cut off from each other. In the aftermath of World War I, there was a serious movement to unify North Tyrol with Bavaria.Carsten, Francis Ludwig. ''The First Austrian Republic: 1918-1938''. Gower, 1986. P. 3. North Tyrol borders Salzburg in the east, the German federal state of Bavaria in the north, Vorarlberg to the west, the Swiss canton of Graubünden (Grison) to the southwest, and South Tyrol in Italy to the south.
