The cuprous ion has a completely filled $d$-orbital,while the cupric ion has an incompletely filled $d$-orbital.

Vedclass · Answer

(B) The electronic configuration of the cuprous ion $(Cu^+)$ is $3d^{10}$,which means its $d$-orbital is completely filled. Due to the absence of unpaired electrons,$d-d$ transitions are not possible,making it colorless.The electronic configuration of the cupric ion $(Cu^{2+})$ is $3d^9$,which means its $d$-orbital is incompletely filled (contains one unpaired electron). This allows for $d-d$ transitions,making it colored.

Why is the cuprous ion colorless while the cupric ion is colored?
