Who Discovered Gold?

Who Discovered Gold?
Introduction Gold is a chemical element, the most ductile and malleable of all pure metals in the world. It is found in grains or nuggets in rocks and other natural formations. Gold has a bright yellow color. The hue varies from one type of gold to another, as does its value. Arabian gold and Bangkok gold may be considered superior to Italian or Chinese gold. Nothing on earth is more fascinating and desirable to humans than gold. Because gold occurs in an uncompounded form, it was probably the first metal ever discovered and used by man. Discovery and Early Use of Gold Gold occurs in various parts of the world. No single person discovered gold but there are many traces of its use by ancient peoples. One early reference to it was made by Tushratta, a king of Mitanni (now northern Syria) in 2600 BC. He remarked that there was more gold than dust in Egypt. Such abundance of gold especially in Nubia made Egypt a rich country. By 1500 BC the metal was being used as a means of exchange in...

Who Discovered Carbon?

Who Discovered Carbon?
Represented by the atomic number 6 and the symbol C, carbon is an important chemical element classified as tetravalent and nonmetallic. It is one of the longest existing elements known today. The most popular allotropes of carbon are amorphous carbon, diamond and graphite. It is widely used in the petrochemical industry, specifically in producing kerosene as well as gasoline. In addition to these interesting details, it is good to learn other valuable information about this all-important element such as who discovered carbon. The Discovery of Carbon Who discovered carbon? Although this element was discovered in prehistory, several individuals contributed to a clearer knowledge about its different properties and characteristics. For instance, French scientist Rene A. F. de Reaumur first showed in 1722 that through the absorption of carbon, it was possible to transform iron into steel. By 1772, the father of modern chemistry Antoine Lavoisier discovered that diamonds were in a way one form...

Who Discovered the Constellation Virgo?

Who Discovered the Constellation Virgo?
Introduction The Latin origin of the word Virgo denotes a “virgin” or young woman. Presently, the autumn equinox is within Virgo. About 400 years from now it will move to Leo. Virgo is one of the biggest constellations in the sky, and contains many galaxies. It comes after Leo in the east. You can see it in the southern part of the sky in spring in middle latitudes of the northern hemisphere. History and Symbolism of Virgo Who discovered the constellation Virgo? Like several other major star formations, Virgo was known to the Sumerian and Babylonian astronomers. From them the knowledge of the sign passed on to the Egyptians, Greeks and other peoples in Asia Minor and the Mediterranean. Virgo is listed in a Babylonian astrology compendium known as the Mul Apin. These tablets are believed to be about 3,000 years old. The Mul Apin names Virgo as “absimu,”“the Furrow.” It was identified with the Babylonian and Akkadian goddess Shala. Virgo’s eastern stars including Spica were...

Who Discovered the Element Lithium?

Who Discovered the Element Lithium?
Represented by the atomic number 3 and symbol Li in the periodic table, lithium is described as a silver-white and soft metal. It is one of the alkali metals, which is generally considered the lightest amongst the various kinds of metals. Likewise, it is also the least dense amongst the different solid elements. More than anything else, it is known for its important uses in the fields of medicine, electronics and general engineering. The Discovery of Lithium Who discovered the element lithium? In 1817, a Swedish chemist named Johan August Arfwedson became the very first person to discover this chemical element. The result came from his analysis of a petalite ore. Before that, a Brazilian scientist named Jose Bonifacio de Andrade e Silva discovered lithium aluminum silicate or petalite in 1800. This finding was instrumental, particularly in the discovery of lithium. Swedish chemist Jons Jakob Berzelius named it ‘lithos,’ which later on was standardized as lithium. Additional Facts and...

Who Discovered Tin?

Who Discovered Tin?
One of the most amazing facts about tin is its usage since ancient times. There is evidence that Stone Age men used it 3,500 years ago. How the ancients discovered it is still a mystery. Discovery and History of Tin During the Late Stone Age people learned to put tin and copper together to produce bronze. Bronze was much easier to manipulate than copper and its use became widespread. This discovery ushered in the Bronze Age, which influenced the Egyptian, Mesopotamian and Indus Valley civilizations. Everything from weapons to utilities were fashioned from these materials. One of the oldest tin mining sites is in the Taurus Mountains in Turkey. An assessment of the facts about tin will show that usage of tin as a pure metal didn’t start until 600 BC. Tin was used heavily during the Medieval Ages, with Cornwall being one of the leading producers. Tin were also discovered and used in Asia. China, Laos and Indonesia were among the countries that also utilized the element. By 1931, the International...
