Electron Configurations

Front

What is an electron configuration?

Back

An electron configuration is the distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What is the order of filling orbitals in electron configurations?

Back

The order of filling orbitals follows the Aufbau principle: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, etc.
