Explanation
Why this works
Stem being answered: Evaluate a student answer to Determine Proton Neutron And Electron Numbers For Atoms: what must be included for full A-Level credit? Route focus: particles-and-radiation / Particles.
Key vocabulary for this item: determine, proton, neutron, electron, numbers, atoms, ions. Written check: state the principle, apply it to the named context, and close with the requested conclusion.
The explanation should keep the answer tied to these exact words rather than a general physics summary, using units, graph evidence or equation reasoning only when they are relevant to the stem.
