Electron configuration and Orbital Notation

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What is orbital notation?

Back

A way to represent the electron configuration of an atom using arrows to indicate the spin of electrons in orbitals.
