Free element

Chemical elements not bound to other elements or compounds

In chemistry, a free element is a chemical element that is not combined with or chemically bonded to other elements. Examples of elements which can occur as free elements include the oxygen molecule (O2) and carbon.[1] They hardly ever bond with other atoms.[citation needed] Other examples of free elements include the noble metals gold and platinum.[2]
