Physics explains why gold stays pristine
Scientists have discovered why gold remains pristine and does not oxidize like other metals. The arrangement of atoms on gold's surface prevents reactions with oxygen, which is responsible for tarnishing in other metals. This understanding could have implications for various applications in materials science.
- ▪Gold does not react with air, unlike metals such as steel and copper.
- ▪Researchers found that the surface atoms of gold rearrange in a way that hinders oxidation.
- ▪Without this atomic rearrangement, gold would begin to oxidize within seconds.

News Physics Physics explains why gold stays pristine Rearrangement of atoms on the metal’s surface helps prevent reactions with oxygen Unlike other metals, which oxidize in air, gold (pictured) doesn't react. Now scientists have a better understanding of why.
