Reading: Atomic Bonds | Geology

A diamond crystal is held together by nothing but extremely strong covalent bonds in all directions, which makes diamond a very hard mineral, the hardest known. Metallic bonds. Gold forms a naturally occurring mineral of more or less pure gold, Au, held together by another type of bond, the metallic bond.

Diamond Description

Diamond''s characteristic chemical composition and crystal structure make it a unique member of the mineral kingdom. Diamond is the only gem made of a single element: It is typically about 99.95 percent carbon. The other 0.05 percent can include one or more trace elements, which are atoms that aren''t part of the diamond''s essential chemistry.
