The website discusses how gold remains untarnished due to the rearrangement of surface atoms, which hinders oxidation. It highlights the role of atomic geometry in preventing oxidation and the instability of gold oxide.
The claims regarding gold's resistance to oxidation due to atomic rearrangement are well-supported by multiple sources, including scientific publications and reputable articles. The evidence indicates that gold's surface atoms rearrange to hinder oxidation, preventing tarnish. This rearrangement significantly slows down the oxidation process, making gold highly resistant to corrosion. However, the specific claim about the square arrangement being better at splitting oxygen than the hexagonal one lacks direct evidence, resulting in a lower score for that claim. Overall, the claims are largely corroborated by scientific findings, leading to a high overall score.
Individual Claims

True
Physics
Atoms on the surface of gold rearrange into a geometry that hinders oxidation.
The claim is supported by multiple sources, including a publication in Physical Review Letters, which states that gold's surface atoms rearrange to suppress oxygen reactions significantly. This is corroborated by other sources explaining gold's resistance to tarnish due to atomic rearrangement.

Without rearrangement, gold would begin to oxidize in seconds.
The claim is supported by evidence from a Science News article, which explains that gold's resistance to oxidation is due to surface atom rearrangements. Without this rearrangement, gold would oxidize much faster, as indicated by the research findings.

The square arrangement of gold atoms is better at splitting oxygen than the hexagonal one.
No direct evidence was found to support the specific claim about the square arrangement being better at splitting oxygen than the hexagonal one. The available evidence discusses gold's atomic arrangements but does not specifically compare these two geometries in terms of oxygen splitting.
