Q. Cuprous ion is colourless, while cupric ion is coloured because

Both have impaired electrons in d-orbital

Cuprous ion has incomplete d-orbital and cupric ion has a completed d-orbital

Both have half-filled p and d-orbitals

Cuprous ion has a completely filled d-orbital and cupric ion has an incomplete d-orbital

Cuprous ion $(C u^{+}) 3 d^{10}$ Completely filled d subshell
