) are central to modern solar energy conversion and light-driven organic synthesis due to their long-lived excited states. Summary Table Key Property Common Use Extreme malleability; Relativistic color Electronics, Jewelry, Nanomedicine Silver (Ag) Highest thermal/electrical conductivity Photography (historically), Antimicrobials Palladium (Pd) Hydrogen "sponge" Hydrogenation, Catalytic converters Platinum (Pt) High melting point; Bio-compatibility Chemotherapy, Fuel cells Rhodium (Rh) Extreme corrosion resistance NOxcap N cap O sub x reduction in vehicles
electrons move at speeds approaching a significant fraction of the speed of light. This causes the orbitals to contract and become more stable. Expansion: Simultaneously, the Chemistry of Precious Metals
