Gold in bullion form is commonly ' four nines', 99.99% pure gold. Gold coins are often of lower gold content - as low as 21 ct in some cases. This helps the coin resist wear.

Why gold found as pure elements in rocks?
Gold does not readily react with other elements, so it is often found in 'pure' form, also the rocks surrounding the gold prevent it from oxidation.
Are there different forms of gold?
Gold is the most beautiful and desirable of all the chemical elements. Gold is one of the few chemical elements to be found in its natural state. When found it is a metallic yellow in colour. Gold is found as nuggets, dust or little chips. It is used today in many things such as jewlerry, crowns, etc.
What elements are usually found with gold ore?
copper, silver, nickel, iron...
Why are gold silver and copper considered native elements?
Gold, silver, and copper are considered native elements because they occur in nature in their pure form. They are not chemically combined with any other elements and can be found in Earth's crust as metallic mineral deposits. This is in contrast to other elements, which are often found in nature in the form of compounds or minerals.
Why is pure gold more likely to be found in the ground than pure sodium?
Gold does not easily bond with other elements found in the earth. However, sodium bonds quite easily with other common elements such as nitrogen and chlorine, so to find pure sodium is unlikely.
What elements found in corals?

Is gold found in a covalent compound?
no, covalent compounds can only include non-metal elements and gold (Au) is a metal element
Is there gold on the planet mars?
Most likely yes. All elements found on Earth can probably be found on Mars. However, trying to retrieve the gold from Mars would cost more than the gold is worth.
Is gold radioactive?
No isotope of silver ordinarily found in nature is radioactive. Like all elements, silver has synthetic radioactive isotopes.Silver is not radio active, none of silver's isotopes have radio activity.ur welcome!

What elements create gold?
Gold. Gold is an element, so it cannot be created from other elements.
Which elements found in free elemental state?
Ag(silver), Au(gold), Pt(platinum), Cu(copper) are found in free state
