3.3—Draw dot-and-cross diagrams to show electrons in cations and anions

Be able to draw dot-and-cross diagrams to show electrons in cations and anions.

Use —draw dot-and-cross diagrams to show electrons in cations and anions to connect the rule to the data and decision in the question.

This matters because —draw dot-and-cross diagrams to show electrons in cations and anions determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —draw dot-and-cross diagrams to show electrons in cations and anions to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Draw dot-and-cross diagrams to show electrons in cations and anions is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
