Gold - Research Paper ExampleGold is a leaden part having a shiny, soft and malleable surface. Its chemical symbol is Au which comes from a Latin word Aurum. It has an atomic number of 79. Gold is among the non-reactive metal, thus, it many working(a) uses in manufacturing industries and natural environments. It has rust resistance i.e. does not react with oxygen. It is a good conductor of electricity being able to convey a rattling tiny electrical current in temperature ranging from -550 to +2000. 1 This metal is among the most ductile metals, thus, it allows to be molded into very small threads or wires without breaking. Furthermore, favorable is malleable. This makes it possible to be shaped into extraordinary thin sheets. It is known to be the least absorptive material, but most reflective of infrared energy. Gold with a high purity has the capability of reflecting 99 percent of infrared rays. Also, bills is among the best instigate conductors or thermal energy. This makes it to be used to transfer heat away from very delicate instruments, like electronics. Gold alloys, being the most tenacious and long performing material that is used to guard electronics against high temperatures produced by them.It occurs in its compound and also in native state (Its Free State). 2 Gold is not combined with any other element in nature. Telluride (a compound of element Tellurium) is the most common compounds of gold. For example, gold telluride (AuTe 2) is mostly composed of mineral calavarite.Also, gold is found in Nuggets and chunks large enough to see. 3 This enables people to mine gold by picking and collecting it from the rivers and streams. Gold estimation abundance in the earth crust is around 0.005 Parts per Million. 3 This makes a very small fraction as compared to Iron and other metals.Many people believe that, about 70 million tons of gold are found in oceans. This has led to many ocean
