3.21—Metallic bonding is the strong electrostatic attraction between metal ions and the delocalised electrons

Know that metallic bonding is the strong electrostatic attraction between metal ions and the delocalised electrons.

Use —metallic bonding is the strong electrostatic attraction between metal ions and the delocalised electrons to connect the rule to the data and decision in the question.

This matters because —metallic bonding is the strong electrostatic attraction between metal ions and the delocalised electrons determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —metallic bonding is the strong electrostatic attraction between metal ions and the delocalised electrons to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Metallic bonding is the strong electrostatic attraction between metal ions and the delocalised electrons is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
