Calculate the numerical difference between the Effective Atomic Number (EAN) of Platinum in the comp — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Both complexes have a central metal in the $+4$ oxidation state and a coordination number of $6$. EAN of $Pt$ in $[Pt(NH_3)_6]^{4+} = 78 - 4 + 2(6) = 74 + 12 = 86$ (matches Radon). EAN of $Pd$ in $[Pd(NH_3)_6]^{4+} = 46 - 4 + 2(6) = 42 + 12 = 54$ (matches Xenon). The numerical difference is $86 - 54 = 32$.
