The shorthand electron configuration of radon (Rn) is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p⁶. This notation indicates that radon has a complete outer shell of electrons, with the electron configuration of the noble gas xenon (Xe) preceding it, plus additional electrons in the 4f, 5d, 6s, and 6p orbitals. Radon is a noble gas and is located in group 18 of the Periodic Table.
The short hand configuration is also called noble gas configuration because it mimics the electron configuration of noble gases, which are chemically stable and have full valence shells. By using noble gas configurations, we can easily represent the electron arrangement of elements without writing out the entire electron configuration.
