How to write it
Place 52 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. Tellurium sits in period 5, group 16, 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 5p4.

Tellurium electron configuration FAQ
What is the electron configuration of tellurium?
1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁴. Shorthand (noble gas) notation: [Kr] 4d¹⁰ 5s² 5p⁴.
What is the noble gas configuration of tellurium?
[Kr] 4d¹⁰ 5s² 5p⁴. The bracket stands for the Kr core electrons.
How many valence electrons does tellurium have?
6 (outer shell (n = 5)).
How many unpaired electrons does tellurium have?
2 in the ground state, following Hund’s rule. An atom with unpaired electrons is paramagnetic.
What is the electron configuration of Te2−?
[Kr] 4d¹⁰ 5s² 5p⁶ (54 electrons).
