Vedclass · Answer

(A) The formula for $EAN$ is: $EAN = Z - x + 2n$,where $Z$ is the atomic number,$x$ is the oxidation state,and $n$ is the coordination number.For the complex $[Co(NH_3)_6]^{3+}$:Atomic number of $Co$ $(Z)$ = $27$.Oxidation state of $Co$ $(x)$: $x + 6(0) = +3 \implies x = +3$.Coordination number $(n)$ = $6$.$EAN = 27 - 3 + 2(6) = 24 + 12 = 36$.

The effective atomic number $(EAN)$ of cobalt in the complex $[Co(NH_3)_6]^{3+}$ is
