Fundamentals of Electron Configuration
To effectively use the gizmo and its answer key, it's essential to understand the core concepts of electron configurations.
What Are Electron Configurations?
Electron configurations describe how electrons are distributed among the various orbitals of an atom. The arrangement determines many properties of the element.
Principles Governing Electron Configuration
Several fundamental principles guide electron arrangements:
- Aufbau Principle: Electrons occupy the lowest energy orbitals available.
- Pauli Exclusion Principle: Each orbital can hold a maximum of two electrons with opposite spins.
- Hund’s Rule: Electrons fill degenerate orbitals (orbitals of the same energy) singly before pairing.
Electron Shells and Subshells
Electrons occupy shells (principal energy levels), labeled n=1, 2, 3, etc., and within these shells are subshells: s, p, d, and f.
| Shell (n) | Subshells | Max Electrons per Subshell | Max Electrons per Shell |
|------------|------------|-----------------------------|-------------------------|
| 1 | 1s | 2 | 2 |
| 2 | 2s, 2p | 8 | 8 |
| 3 | 3s, 3p, 3d | 18 | 18 |
| 4 | 4s, 4p, 4d, 4f | 32 | 32 |
