Answer:
\[C{{u}^{2+}}\] ion \[(3{{d}^{9}})\]
has one half filled d-orbital. Therefore, it has an urge to take part
in d?d transition. The compounds containing \[C{{u}^{2+}}\] ion
(e.g., \[CuS{{O}_{4}}.5{{H}_{2}}O\]) are coloured. \[Z{{n}^{2+}}\] ion \[(3{{d}^{10}})\]
has completely filled d-orbitals and there is no scope for any electron
transition. Therefore, \[Z{{n}^{2+}}\] salts are white and not coloured.
