Question

Formation
of Coloured
Ions​

Answer 1

The colour of the transition metal ions is due to the presence of unpaired or incomplete d-orbitals. The absorption of visible light and hence coloured nature of the transition metal cations is due to the promotion of one or more unpaired d-electron from a lower to a higher level within the same d-subshell
