Rhodium (Rh), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, predominantly used as an alloying agent to harden platinum. Rhodium is a precious, silver-white metal, with a high reflectivity for ligh

1. Rhodium: This is one of the most expensive metals on the earth. Nearly 80% of the world’s rhodium has been mined in South Africa only. Rhodium is largely used in the form of catalysts in the chemical industry. It is used for making nitric acid, acetic acid and hydrogenation reactions, among others. The price of Rhodium is much higher than gold.
2. Platinum: The metal offers outstanding resistance against corrosion. It is widely and extensively used for jewellery. Platinum is also used for several types of weapons, dental equipment, and aeronautics as the metal offers high level of resistance. Platinum is extensively used for jewellery. Its significant use is also in catalytic converters for cars, trucks as well as for buses. It is popular for its stunning luster and shiny appearance.
3. Palladium: The metal was discovered way back in 1803. Palladium was named after the asteroid Pallas. It is quite hard and offers stunning resistance to scratches. It is used for catalytic reactions in industry that may include hydrogenation of unsaturated hydrocarbons. The price of palladium per ounce is $1037.05 and for 1 kg it is $33,341.93.
4. Ruthenium: It is largely found in the North and South America mountains. The metal is vastly used in the electronics industry in the form of a plating material for electrical connections
5. Gold: The yellow metal is witnessing a surge in prices and emerged one of the most sought after all across the globe. It is one of the most desired metals globally offers great durability and flexibility.
