77 protons, 115 neutrons.
Silver, just like Iridium-191
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.)
Iridium is a metal element. Atomic number of it is 77.
Platinumit has 6 naturally occurring isotopes: 190 (78 protons and 112 neu-trons), 192 (78 protons and 114 neutrons), 194 (78 protons and 116 neu-trons), 195 (78 protons and 117 neutrons), 196 (78 protons and 118 neu-trons), 198 (78 protons and 120 neutrons).
By one mole of osmium, we can say that it contains 6.02 x 10 23 atom. So we can say that one osmium atom contains 76 electrons: 2, 8, 18, 32, 14, 2.

The radiation emited is gamma ray
Iridium-192 is used in brachytherapy because it has particular properties, although it is bad because it only has a half life of 74 days and so has to be changed approx. three times a year

The atomic number of iridium (Ir) is 77.The atomic weight of Ir is 192.22 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
There are 78 protons and 78 electrons present in a platinum atom. There are also at least 114 neutrons in the five stable isotopes. 192 Pt = 114 194 Pt = 116 195 Pt = 117 196 Pt = 118 198 Pt = 120
This is Logan Steckler. The answer from best to last is Lead, then concrete
Some iridium applications are: - alloy for fountain pen - components of catalysts - electrodes for sodium hydroxide production - spark plugs - crucibles highly resistant to corrosion - component in many expensive alloys resistant to corrosion, heat at and erosion - the isotope Ir-192 is a source of gamma radiation - the standard kilogram is an alloy of platinum with iridium
Iridium has an atomic mass of 192 (192.217)
