What metals are used to make jewelry?
Gold is a beautiful yellow metal. It forms chemical compounds with difficulty and is chemically stable in air, water and acids. Gold is highly reflective, polishes well, and has high ductility. Silver is a white metal that practically does not change under the influence of oxygen at room temperature, but due to the presence of hydrogen sulfide in the air, over time it becomes covered with a dark coating of silver sulfide. Has good malleability. Platinum - has a white-gray color, practically insoluble in water and acids, with the exception of hot aqua regia. Platinum is ductile, highly polished, and highly reflective.
