17.1—Transition metals are d-block elements that form one or more stable ions with incompletely-filled d-orbitals

Know that transition metals are d-block elements that form one or more stable ions with incompletely-filled d-orbitals.

Use —transition metals are d-block elements that form one or more stable ions with incompletely-filled d-orbitals to connect the rule to the data and decision in the question.

This matters because —transition metals are d-block elements that form one or more stable ions with incompletely-filled d-orbitals determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —transition metals are d-block elements that form one or more stable ions with incompletely-filled d-orbitals to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Transition metals are d-block elements that form one or more stable ions with incompletely-filled d-orbitals is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
