An original Iridium (Ir) Atomic Number 77 Periodic Table of Elements Design.
Iridium is a chemical element with symbol Ir and atomic number 77. A very hard brittle silvery-white transition metal of the platinum group iridium is generally credited with being the second densest element (after osmium). It is also the most corrosion-resistant metal even at temperatures as high as 2000 C. Although only certain molten salts and halogens are corrosive to solid iridium finely divided iridium dust is much more reactive and can be flammable.
