Gold (Au), chemical element, a dense lustrous yellow precious metal of Group 11 (Ib), Period 6, of the periodic 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.
In the previous two chapters you have learnt about the spheres of the Earth especially the lithosphere. The lithosphere consists of rocks, which contain minerals. Minerals are natural compounds formed through geological processes. A mineral could be a pure element, but more often minerals are made up of many different elements combined.

Geological major elements are defined as those elements that compose 95% of the earth''s crust. They are Si, Al, Ca, Mg, Na, K, Ti, Fe, Mn and P. Major element (whole rock) geochemistry has traditionally been done by Xray fluorescence (XRF) but such analysis can now be performed by inductively coupled plasma (ICP) technologies.

The quick answer is: Diamond is a pure element, carbon; gold is a pure element, gold; and rust is a compound, Iron Oxide, of iron and Oxygen. Diamond is pure elemental carbon, compressed to its crystal form, under extreme heat and pressure deep within the Earth. The symbol for carbon is C. Gold is also an element, in and of itself.
