What is Noble Metals?
Metals that are resistant to corrosion and oxidation in moist air, including gold, silver, platinum, palladium, rhodium, iridium, osmium, and ruthenium. Their resistance to chemical attack makes them valuable in jewelry, catalysts, and electrical contacts.

Metals that are resistant to corrosion and oxidation in moist air, including gold, silver, platinum, palladium, rhodium, iridium, osmium, and ruthenium. Their resistance to chemical attack makes them valuable in jewelry, catalysts, and electrical contacts.
Noble metals are used in: catalysis (Pt and Pd in catalytic converters, Rh in auto catalysts, Pd in hydrogenation, Pt in fuel cells), jewellery (Au, Pt, Ag), electronics (Au in connectors, Ag in circuit boards), dentistry (Au, Pd alloys), medicine (Pt in cisplatin, Rh in radiotherapy), and as standa…
Noble metals themselves are generally of low toxicity in metallic form. However, soluble forms (chloroplatinate(IV) salt, potassium tetrachloroaurate) can cause allergic sensitisation (platinum salt asthma). Platinum-based anticancer drugs (cisplatin) are highly toxic (nephrotoxicity, ototoxicity, n…
