Lawrie Ryan and Roger Norris Solutions for Chapter: Transition Elements, Exercise 10: Question

What do degenerate atomic orbitals mean?

Explain why an octahedral complex of a transition element is coloured.

Draw the non-degenerate 3d orbitals in a ${\mathrm{Ni}}^{+}$ ion on a diagram. The electrons should be shown in the configuration that gives the lowest possible energy.

A solution of ${\mathrm{Sc}}^{3+}$ ions is colourless. Suggest a reason for this.

A solution of ${\mathrm{Zn}}^{2+}$ ions is colourless. Suggest a reason for this.
