Is iridium a mixture?
Natural iridium consists of a mixture of two stable isotopes, iridium-191 (37.3 percent) and iridium-193 (62.7 percent). The chemistry of iridium centres on oxidation states of +1, +3, and +4, though compounds of all states from 0 to +6 are known with perhaps the exception of +2.
Is iridium an element compound or mixture?
Iridium is a chemical element with the symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, iridium is considered to be the second-densest naturally occurring metal (after osmium) with a density of 22.56 g/cm3 as defined by experimental X-ray crystallography.
Is iridium a compound?
Please visit the Iridium element page for information specific to the chemical element of the periodic table. Iridium is an element with atomic symbol Ir, atomic number 77, and atomic weight 192.217. Iridium atom is a cobalt group element atom and a platinum group metal atom.
What type of element is iridium?
transition metal
Iridium is a hard, brittle, lustrous, dense, transition metal of the platinum family. It is silvery-white and it is notable for being the most corrosion resistant element known. It is unaffected by air, water and acids.

Is iridium a solid liquid or gas?
Iridium is a chemical element with symbol Ir and atomic number 77. Classified as a transition metal, Iridium is a solid at room temperature.
What is a diamagnetic element?
A diamagnetic substance is one whose atoms have no permanent magnetic dipole moment. When an external magnetic field is applied to a diamagnetic substance such as bismuth or silver a weak magnetic dipole moment is induced in the direction opposite the applied field.
Is Iridium a solid liquid or gas?
What is complex compound of iridium?
Two of the most important iridium(I) complexes are Vaska’s compound, IrCl(CO)(PPh3)2, which is a good model for the activation and oxidative addition of simple molecules (e.g., hydrogen, chlorine, oxygen, and HCl), and [Ir(COD)Cl]2 (COD = cyclooctadiene-1,5), which is a catalyst.
