3.16—The principles of the electron-pair repulsion theory, used to interpret and predict the shapes of simple molecules and ions

Understand the principles of the electron-pair repulsion theory, used to interpret and predict the shapes of simple molecules and ions.

Use —the principles of the electron-pair repulsion theory, used to interpret and predict the shapes of simple molecules and ions to connect the rule to the data and decision in the question.

This matters because —the principles of the electron-pair repulsion theory, used to interpret and predict the shapes of simple molecules and ions determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the principles of the electron-pair repulsion theory, used to interpret and predict the shapes of simple molecules and ions to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The principles of the electron-pair repulsion theory, used to interpret and predict the shapes of simple molecules and ions is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
