The Chemical Properties of GoldActforlibraries.org
The name gold is derived from the AngloSaxon word geolo, which not surprisingly means yellow. On the Periodic Table of the Elements, the chemical symbol for gold is AU. As with many symbols used on the Periodic Table, this comes from the Latin name Aurum, meaning Glowing Dawn, or Shining Dawn depending on your particular translation.

Chemical substanceWikipedia
An element is a chemical substance made up of a particular kind of atom and hence cannot be broken down or transformed by a chemical reaction into a different element, though it can be transmuted into another element through a nuclear reaction.This is so because all of the atoms in a sample of an element have the same number of protons, though they may be different isotopes, with differing

Gold's Chemical PropertiesGuide from BullionVault
Gold is a chemical element so it can only be found, not manufactured. It is largely inert, which means: i It is almost totally immune to decay, ii it is not very useful in any industrial/chemical processes which use it up and iii it is easy to store cheaply for long periods.

Chemicals Used in Gold PlatingSciencing
Gold is a stable metal and it takes harsh chemicals to accomplish this. Usually gold is complexed with cyanide, called cyanaurate, although techniques using sulfites and thiosulfites exist. There are many proprietary formulae for these solutions. In tank electroplating, cyanaurate is dissolved in an acidic bath that receives the electrodes.
