Gold (Au), chemical element, a dense lustrous yellow precious metal of Group 11 (Ib), Period 6, of the periodic table.Gold has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form.

Gold is a chemical element with symbol Au (from Latin aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.Chemically, gold is a transition metal and a group 11 element.It is one of the least reactive chemical elements and is solid under

gcse 1. Introduction to the Extraction of Metals method

1. Introduction to the extraction of metals. What methods can be used in extracting metals from mineral ores? The Earth's crust contains many different rocks.. Rocks are a mixture of minerals and from some we can make useful substances.. A mineral can be a solid metallic or nonmetallic element or a compound found naturally in the Earth's crust.
