A science centre is producing two displays about a simple molecule. The requirements are shown in the table.
| Display | Requirement |
|---|---|
| Electron display | Identify which outer-shell electrons form each bond and which atom each electron came from. |
| Shape display | Allow the bonds in the three-dimensional structure to be examined. |
Suggest the most suitable representation for each display. Give one limitation of each representation you suggest.
122 exam-style questions on OCR GCSE Chemistry 2.2 Bonding, covering 2.2.1 Metals, non-metals and the Periodic Table, 2.2.2 Types of chemical bonding and dot and cross diagrams, 2.2.3 Limitations of bonding models, and 2.2.4 Reactivity, atomic number and the modern Periodic Table. Each one has a worked solution and a mark scheme showing where the marks go.
