How to write it
Place 60 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. Neodymium sits in period 6, in the f-block, so its last electron enters a f subshell. Replacing the inner electrons with the previous noble gas gives the shorthand [Xe] 4f4 6s2.

Neodymium electron configuration FAQ
What is the electron configuration of neodymium?
1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f⁴ 6s². Shorthand (noble gas) notation: [Xe] 4f⁴ 6s².
What is the noble gas configuration of neodymium?
[Xe] 4f⁴ 6s². The bracket stands for the Xe core electrons.
How many valence electrons does neodymium have?
2 (2 in the outer s subshell).
How many unpaired electrons does neodymium have?
4 in the ground state, following Hund’s rule. An atom with unpaired electrons is paramagnetic.
What is the electron configuration of Nd3+?
[Xe] 4f⁴ (57 electrons).
