Edexcel IAL Chemistry AS 3.3 Ionic dot-and-cross diagrams
Determine each ion charge and formula ratio first, then show only outer electrons with distinct symbols and place the complete electron shells inside charged brackets.
How this is tested
- Draw ionic dot-and-cross diagrams with correct ion ratio, brackets and charges.
- Show transferred outer electrons distinctly and complete each anion electron shell.
