5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is pauli exclusion principle?Show answer
An orbital holds at most two electrons, and they must have opposite spins (no two electrons in an atom can have the same set of quantum numbers).
What is hund's rule?Show answer
Within a set of degenerate (equal-energy) orbitals, electrons occupy them singly with parallel spins before any pairing occurs, which minimises repulsion.
What is q1?Show answer
State the maximum number of electrons that can occupy a single d subshell. [1 mark]
What is q2?Show answer
Write the spectroscopic electronic configuration of a copper atom (). [1 mark]
What is q3?Show answer
State Hund's rule. [1 mark]
