so the thing is that to find the valency of iridium the thing that is necessary is that you see the periodic table where is it after finding its atomic number that is 77 we can easily calculate its valency as per bihr bury scheme. we know that there should be 2 8 18 and 32 electrons but the thing is that the outermost shell of element can have less than or equal to 8 electrons. the atomic number should be divided in such manner like 2,8,8,8,8,8,8,8,8,8 after this we will have 3 left so that goes to the outermost shell so what is the valency of iridium its 3
