How to write it
Place 54 electrons into subshells in the Aufbau order (1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p), filling s with 2, p with 6, d with 10 and f with 14. Xenon sits in period 5, group 18, in the p-block, so its last electron enters a p subshell. Replacing the inner electrons with the previous noble gas gives the shorthand [Kr] 4d10 5s2 5p6.

Xenon electron configuration FAQ
What is the electron configuration of xenon?
1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶. Shorthand (noble gas) notation: [Kr] 4d¹⁰ 5s² 5p⁶.
What is the noble gas configuration of xenon?
[Kr] 4d¹⁰ 5s² 5p⁶. The bracket stands for the Kr core electrons.
How many valence electrons does xenon have?
8 (full outer shell).
How many unpaired electrons does xenon have?
0 in the ground state, following Hund’s rule. With all electrons paired, the atom is diamagnetic.
