Vedclass · Answer

(A) Step $1$: Identify the atomic number $(Z)$ of $Cu$ $(Z = 29)$.Step $2$: Determine the oxidation state of $Cu$ in $[Cu(NH_3)_4]^{2+}$. Let it be $x$. $x + 4(0) = +2$, so $x = +2$.Step $3$: Calculate the number of electrons in the metal ion: $Z - 	ext{oxidation state} = 29 - 2 = 27$.Step $4$: Calculate the number of electrons donated by ligands: $4 	imes 2 = 8$.Step $5$: $EAN = (Z - 	ext{oxidation state}) + 	ext{electrons donated by ligands} = 27 + 8 = 35$.
