Vedclass · Answer

(A) Metal ions form colourless compounds if they have a $d^0$ or $d^{10}$ electronic configuration (i.e.,no unpaired electrons).$Zn^{2+}$ has a $3d^{10}$ configuration (fully filled,no unpaired electrons).$Cu^{+}$ has a $3d^{10}$ configuration (fully filled,no unpaired electrons).Since both $Zn^{2+}$ and $Cu^{+}$ have $d^{10}$ configurations,they form colourless compounds.Therefore,the correct option is $A$.

Which pair of metal ions in their respective oxidation states forms colourless compounds?
