What is the chemical name for rhodium?
Rh
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 light.
Is rhodium a chemical element?
Rhodium is a silver-white metallic element that is highly reflective and resistant to corrosion. It is considered the rarest and most valuable precious metal in the world — well above gold or silver. The name rhodium comes from the Greek word “rhodon,” meaning rose, named for the rose-red color of its salts.

What is rhodium chemical properties?
Rhodium is a silver-white metal. It has a melting point of 1,966°C (3,571°F) and a boiling point of about 4,500°C (8,100°F). Its density is 12.41 grams per cubic centimeter. Two of the metal’s special properties are its high electrical and heat conductivity.
How do you identify rhodium?
Procedzlre-To 5 ml of a neutral solution in an ordinary test tube add 5 drops of the reagent and place the test tube in a beaker of boiling water for 5 minutes. The appearance of an orange to orange-red colour indicates the presence of rhodium. The limit of rhodium detectable is 0.5 pg per ml.
What is rhodium gold?
Rhodium plated means jewelry made from a base metal of gold, silver, or other alloy that is coated in a thin layer of rhodium for extra strength and luster. Jewelry plated in rhodium is shinier and more durable than other metals. Rhodium plating does not scratch, dent, or corrode and retains its luster.
Does rhodium stick to a magnet?
Rhodium like other members of the platinum group of transition metals is paramagnetic meaning it is only slightly attracted if at all to a strong…
How is rhodium produced?
Production. Rhodium is extracted as a byproduct of platinum and nickel mining. About one-quarter of rhodium production comes from secondary sources, mainly recycled catalytic converters, while the remainder is extracted from ore. Large rhodium producers include Anglo Platinum, Norilsk Nickel, and Impala Platinum.
