The electron configuration for Xenon is written out in the given answer. It starts with the filling of the 1s orbital, followed by the 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 5s, and 5p orbitals. The electron configuration is then abbreviated using the noble gas notation, which represents the electron configuration of the noble gas that precedes Xenon (Krypton in this case), followed by the electron configuration of the remaining orbitals (5s2 4d10 5p6).
