Gold periodictable

Physical CharacteristicsGold is widely present in the Earths crust (0.3 ppm by weight). It is also present in river beds as rock bound gold is released by erosion of rock by running water. Gold also exists in the form of alloy, such as amalgam (with mercury) or with silver. Gold is found in association of pyrites deposits and from quarts and gravels. Naturally, most of the gold present in the Earths crust is in combination with silver. The term electrum is used for gold ore that have silver content of more than
