2 valence electrons are in iridium because iridium is a transition metal.
Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
Iridium has 2 electrons in its outer shell. It belongs to group 9 in the periodic table, which means it has 9 electrons in its valence shell.
Indium has 3 valence electrons.
8 valence electrons- 1s22s2p63s2p6
