Noble metals are a group of metals that exhibit remarkable resistance to corrosion and oxidation in moist air. They are typically characterized by their high value, ductility, and ability to conduct electricity. The primary noble metals include: 1. **Gold (Au)** - Known for its malleability, conductivity, and resistance to tarnish. 2. **Silver (Ag)** - Widely used in jewelry and electronics, though more prone to tarnishing than gold.
