IB Chemistry 1.3.5 Orbitals and electron spin Questions
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
