History of Gold
Nobody knows who picked up a gold nugget for the first time but it has been a highly valued metal since it was discovered. Gold is one of the first metals known and is the basis of currencies in many countries. Gold is highly valuable so in the past people seeked gold during the South African(1885) And California(1948) Gold Rush. Overtime a hallmarking system was made to determine the quality of precious metals like gold.
Gold is used in many different ways. For example, gold was first used in dentistry in 700-600 BC because of its bio-compatibility, malleability, and corrosion resistance. Also, the gold isotope 198Au is used in the medical field to treat cancer, etc. Another way gold is used is for electronics because of its inertness and other physical properties. Lastly, Gold is mostly used for jewelry because it is a precious metal.
Description/ Biological and Geological Uses
Gold is a shiny yellow metal that is highly malleable/ductile. It is a heavy metal with a density of 19.93g cm3. Biologically, gold is not a necessary element for living things but it is in a person's body(100 ppb by weight). Geologically, 2/3 of the Earth's supply of gold is found in South Africa and there is 0.06 ppb by weight in the world.
