3.14—Ionic and covalent bonding are the extremes of a continuum of bonding type

Know that ionic and covalent bonding are the extremes of a continuum of bonding type and be able to explain this in terms of electronegativity differences, leading to bond polarity in bonds and molecules, and to ionic bonding if the electronegativity is large enough.

Use —ionic and covalent bonding are the extremes of a continuum of bonding type to connect the rule to the data and decision in the question.

This matters because —ionic and covalent bonding are the extremes of a continuum of bonding type determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —ionic and covalent bonding are the extremes of a continuum of bonding type to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Ionic and covalent bonding are the extremes of a continuum of bonding type is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
