—Covalent bonding is the strong electrostatic attraction between two nuclei and the shared pair of electrons between them

Understand that covalent bonding is the strong electrostatic attraction between two nuclei and the shared pair of electrons between them, based on the evidence: i the physical properties of giant atomic structures ii electron density maps for simple molecules.

Use —covalent bonding is the strong electrostatic attraction between two nuclei and the shared pair of electrons between them to connect the rule to the data and decision in the question.

This matters because —covalent bonding is the strong electrostatic attraction between two nuclei and the shared pair of electrons between them determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —covalent bonding is the strong electrostatic attraction between two nuclei and the shared pair of electrons between them to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Covalent bonding is the strong electrostatic attraction between two nuclei and the shared pair of electrons between them is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
