Electron Configuration

Electron Configuration is a short-hand way of describing which orbitals in an atom are occupied by electrons.

This page serves as a central jumping off point for electron configuration. Here are the links that you may want to look at:

• Bohr's theory
• Schrödinger’s Theory
• Schrödinger’s Math (a very scaled down discussion and still beyond most high school courses)
• Electrons in the Schrödinger atom (including the first look at electron configuration)
• Electron Configuration and the Periodic Table
• Electrons Configuration and the periodic table - part 2
• Noble gas configurations
• The d and f blocks
• Exceptions in the d block
• Negative ions
• Positive ions
