== Purity ==
The purity of gold in a compound is measured in [[Carat|Karats]], with 24 karats being pure gold. 18 karat gold is three quarters gold, one quarter other [[elements]], and so forth. Gold is usually in alloys because it is soft and pliable.
Gold is one of the few [[native metal]]s, i.e. it is found naturally in its pure metallic form.
