IB Chemistry SL 1.3.5 Orbitals & electron spin
Secure marks on configurations and orbital diagrams by writing ions correctly and applying Pauli exclusion and Hund’s rule to ground states.
How this is tested
- write full or noble-gas electron configurations for species such as S, Cu, and Cr2+
- draw the ground-state orbital diagram for P with 1s, 2s, 2p, 3s, 3p in energy order
- choose the valid orbital diagram by checking spin pairing and single filling before pairing
