Here it is.

Here is an excerpt:

No metal is more malleable or ductile than gold. It can also retain its shape and maintain its appearance longer than many other metals, which helps to explain in historical value.

Gold has one outer shell electron. It will only bond to one other atom under most conditions. Gold is like hydrogen in this respect. However, gold is not as reactive as hydrogen.

Gold exists naturally in an unadulterated state, and can be sorted from sands and gravel through a process known as panning. Its pure state is so soft that to add strength, gold is alloyed with other elements.

Gold can be plated onto particles, and can covert light into heat. This has proven useful as a cancer treatment in tests conducted at Rice University. Gold's biological inertness contributed to its usefulness.
