There are two different isotopes of iridium, known as iridium-191 and iridium-193, which differ in their neutron count. Iridium-191 has 115 neutrons, while iridium-193 has 117 neutrons. These isotopes have different nuclear properties and stability, leading to various applications in fields such as medicine and industrial radiography. The diversity in isotopes is a common characteristic of many elements, resulting from the unique configurations of protons and neutrons in atomic nuclei.
Iridium is a transition metal very dense, practically unreactive, resistant to corrosion, has many oxidation states and natural isotopes, etc.
Iridium is a metal element, atomic number 77. There are two stable isotopes, 191 and 193. Symbol for Iridium is Ir. It is one of the densest elements known. Much more info in Wikipedia entry for 'Iridium'. No cost info given.
Isotopes are atoms of the same element with different numbers of neutrons in their nuclei, resulting in different atomic masses. This is how there can be two different atoms of iridium.
26,4 g iridium is equal to 0,137 mol.
1 atom of iridium has 77 electrons in total.
Iridium is a metal used in the hardening of platinum alloys. It's primary use is in high temperature applications, heavy-duty electrical contacts, and radioactive isotopes are used in cancer treatment. If iridium is used anywhere in the shuttle orbiters or other components of the shuttle stack, its' use is probably minimal and perhaps in electrical contacts.

I do not see an isotope of iridium that does alpha decay. There is an interactive link to isotopes below. (Perhaps I am missing it.)
Germanium has 9 isotopes.
No, there are many stable isotopes.
