What is special about palladium?
A extremely malleable and tarnish-resistant metal, palladium has become a popular metal for jewelry making and catalytic converters because it does not react with oxygen.

Can you eat platinum?
Platinum metal and insoluble salts can produce eye irritation. When ingested or inhaled, platinum metal and insoluble salts are very poorly absorbed (<1% of a dose) and cleared from the body within a week after a single dose.
What is aqua regia?
aqua regia, mixture of concentrated nitric and hydrochloric acids, usually one part of the former to three parts of the latter by volume. This mixture was given its name (literally, “royal water”) by the alchemists because of its ability to dissolve gold. Aqua regia is frequently used to dissolve gold and platinum.
What is palladium jewelry?
Palladium is a precious metal with a white, silvery appearance. It’s one of six metals classed as platinum-group metals (PGMs). Palladium was discovered in 1803 and was first used in jewelry in the late 1930s. Visually, palladium looks similar to platinum.
Does palladium have an odor?
Pd on its own doesn’t have a smell.
What are the chemical properties of palladium?
Palladium is a chemical element with the symbol Pd and atomic number 46. It is a shiny silvery-white metal. At room temperature and pressure, it is in the solid phase. Palladium is resistant to corrosion from air and acids at ordinary temperatures. Some chemical properties of Palladium are given below.
What is the origin of palladium?
Palladium was discovered by William Hyde Wollaston in 1803 at England. Origin of name: named after the asteroid “Pallas” which was discovered at about the same time and from the Greek name “Pallas”, goddess of wisdom.
What is the meaning of palladium?
noun (2) Definition of palladium (Entry 2 of 2) : a silver-white ductile malleable metallic element that is used especially in electrical contacts, as a catalyst, and in alloys — see Chemical Elements Table .
What is melting point of palladium?
Properties: Palladium has a melting point of 1554°C, boiling point of 2970°C, specific gravity of 12.02 (20°C), and valence of 2, 3, or 4. It is a steel-white metal which does not tarnish in air. Palladium has the lowest melting point and density of the platinum metals.
