Compare a guided explanation of the source case with an independent solution. Use the actual case (Explain why the first ionisation energy generally increases across Period 3, and explain the lower value for oxygen than nitrogen.) to state what evidence must be supplied in both versions, and explain how Shielding would prevent a careless conclusion.

Alter exactly one stated species, value, condition, observation, structural feature, or procedural choice in the source case, then evaluate whether the original conclusion still follows. Make the changed case explicit and use . Original case: Explain why the first ionisation energy generally increases across Period 3, and explain the lower value for oxygen than nitrogen.
