Relativistic effects on its outermost electrons explain its color, which is similar to pyrite.
This element is the most malleable and ductile metal. Like platinum, this metal cannot be dissolved by either hydrochloric or nitric acid alone, but can be dissolved by a mixture known as aqua regia (AH-quah REE-jee-ah). Relativistic effects on its outermost electrons explain its color, which is similar to pyrite. For 10 points, name this precious metal whose Latin name, aurum, gives its atomic symbol, Au.
