Iridium Isotopes: 191Ir and 193Ir

What are the properties of the naturally occurring isotopes of iridium?

Naturally occurring iridium has two isotopes, 191Ir and 193Ir. The isotope 191Ir has 77 protons, 114 neutrons, and 77 electrons.

Properties of Iridium Isotopes

The element iridium (Ir) is known to have two naturally occurring isotopes, which are 191Ir and 193Ir. These isotopes differ in their number of protons, neutrons, and electrons. 191Ir Isotope: - Protons: 77 - Neutrons: 114 - Electrons: 77 This means that an atom of 191Ir has 77 protons, 114 neutrons, and 77 electrons. The atomic number of iridium is 77, indicating the number of protons present in its nucleus. The mass number of 191Ir is 191, which is the sum of protons and neutrons. By subtracting the atomic number from the mass number, we can determine the number of neutrons in the isotope. In conclusion, the properties of the naturally occurring isotopes of iridium, specifically 191Ir, include a specific number of protons, neutrons, and electrons that define its atomic structure.
