Description
Why doesn't gold tarnish? A simple answer might be that it's a so-called "noble metal"—its atoms don't like to chemically react with others. But a more complex answer also answers *why* gold atoms are so unreactive. Some of it is due to special relativity, and some is due to a phenomenon called reconstruction.
