Having an accurate answer key ensures that learners can correct mistakes, clarify misconceptions, and build confidence in their knowledge.
Understanding Electron Configurations
Basic Concepts
Electron configuration describes how electrons are arranged around the nucleus of an atom. Electrons occupy specific regions called orbitals, which are grouped into energy levels or shells.
Key points include:
- Principal energy levels (shells): Denoted by numbers (1, 2, 3, etc.).
- Sublevels: Each shell contains sublevels (s, p, d, f).
- Orbitals: Each sublevel contains a specific number of orbitals:
- s: 1 orbital
- p: 3 orbitals
- d: 5 orbitals
- f: 7 orbitals
- Electrons per orbital: Each orbital holds a maximum of 2 electrons, with opposite spins.
Notation and Rules
Electron configurations are written in a specific notation, such as:
- Standard notation: 1s² 2s² 2p⁶ 3s² ...
- Aufbau Principle: Electrons fill orbitals starting from the lowest energy level.
- Pauli Exclusion Principle: No two electrons in the same atom can have identical quantum numbers.
- Hund's Rule: Electrons fill degenerate orbitals singly before pairing.
