Iridium has two naturally occurring isotopes, 191 Ir and 193 Ir. Explain how do I get 77 proton and electron of 77
Answers
Element 77 of Periodic table is Iridium with atomic number 77, atomic weight 192.217. Iridium, symbol Ir, has a Face Centered Cubic structure and Silver color. Iridium is a transition metal element. Know everything about Iridium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure. 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) based on measured density, although calculations involving the space lattices of the elements show that iridium is denser. 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.
