Gold is one of the oldest known chemical elements which has been used for millennia. Its name is derived from the Latin word that means this precious metal. Gold is quite soft metal of bright and shiny yellow color, quite non-reactive and non-toxic. It is not of importance for living organisms. Gold can be found on our planet in its pure natural form, and it can be mined in small amounts in various parts of our planet. This element exists in the waters of the oceans, but in really micro amounts. Gold is used in jewelry production as well as for plating various electronics, watches, and other compounds. It can be used in dentistry, nano technologies, and so on. This metal also has cultural meanings, i.e. being the material for awarding winners, the most successful students, etc.
