17.8—The colour of aqueous ions, and other complex ions, is a consequence of the splitting of the energy levels of the d-orbitals

Understand that the colour of aqueous ions, and other complex ions, is a consequence of the splitting of the energy levels of the d-orbitals by ligands.

Use —the colour of aqueous ions, and other complex ions, is a consequence of the splitting of the energy levels of the d-orbitals to connect the rule to the data and decision in the question.

This matters because —the colour of aqueous ions, and other complex ions, is a consequence of the splitting of the energy levels of the d-orbitals determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the colour of aqueous ions, and other complex ions, is a consequence of the splitting of the energy levels of the d-orbitals to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The colour of aqueous ions, and other complex ions, is a consequence of the splitting of the energy levels of the d-orbitals is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
