Iridium is a metallic element, and Platinum is a different metallic element.
Iridium
Because platinum is non reactive metal
iridium is a family member of the platinum group it is also known as a transition metal.
Iridium is a valuable metal and is rarer than gold or platinum. A search of the internet using "iridium coins" should reveal dozens of sites claiming to have the genuine article.
Platinum, iridium, or osmium, all of which are very low in reactivity.
Yes, iridium is a shiny, silvery-white metal known for its high resistance to corrosion. It has a high melting point and is often used in various industrial applications, including in spark plugs and as a hardening agent in platinum alloys.
Thermocouples that include an alloy of platinum and iridium are often used to measure temperature in a laboratory.
Iridium belongs to the platinum group metals, which include six elements in total: platinum, palladium, rhodium, ruthenium, osmium, and iridium. These metals share similar physical and chemical properties.
Iridium is a metal. It belongs to d-block elements.
Iridium's position on the periodic table indicates that it is a metal.
Iridium is extracted after copper and nickel processing, from a mixture known as anode mud. Once this mixture is dissolved, the iridium is brought to the surface via extraction with organic amines.
Gold and Silver are the best known precious metals. Others are ruthenium, rhodium, palladium, osmium, iridium, and platinum. A metal is considered precious if it is rare.
