It is the most malleable and ductile metal 1 oz. Silver and copper are also in group 11, although gold is not that similar to them chemically. It is a very nonreactive transition metal in group 11, period 6, with 1 valence electron. It is located in the d-block on the periodic table, with platinum to its left and mercury on its right. The Purple of Cassius is a delicate test for auric gold. Gold, symbol Au, has an atomic number of 79. It is metallic, having a yellow color when in a mass, but when finely divided it may be black, ruby, or purple. All gold ever refined would form a single cube twenty meters per side. Of all the elements, gold in its pure state is undoubtedly the most beautiful. Seventy-five percent of all gold ever produced has been extracted since 1910.
Gold’s heat and electrical conductivity qualities – as well as its resistance to heat, oxygen, moisture, and most corrosive agents – make it most applicable in coinage and jewelry. The truth is that atomic weights have changed as a function of time. Atomic weights found within a periodic table one might think are constant. Being that gold is a soft metal, it is strengthened by being alloyed with other metals such as silver and copper. Such was the case when IUPAC recently reviewed elements 113, 115, 117 and 118, and decided to give them official names and symbols (goodbye, ununseptium and hello, tennessine). While the metallic element takes on a yellow color en masse, when finely-divided it can also appear to be black, ruby, or purple in color. Gold has been the standard for monetary exchange in many countries. 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 has several qualities that have made it exceptionally valuable throughout history.
