Atomic Architecture and Periodic Trends · Atomic Structure

Electron Orbitals and Ionisation Energy

Mapping electrons into s, p, and d orbitals and using ionisation energy data to prove shell theory.

Key Questions

  1. 1Why do successive ionisation energies provide evidence for quantum shells?
  2. 2How does the shielding effect influence the reactivity of elements across a period?
  3. 3What causes the specific anomalies in ionisation energy between groups 2 and 3?
