How to write it
Place 22 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. Titanium sits in period 4, group 4, in the d-block, so its last electron enters a d subshell. Replacing the inner electrons with the previous noble gas gives the shorthand [Ar] 3d2 4s2.

Titanium electron configuration FAQ
What is the electron configuration of titanium?
1s² 2s² 2p⁶ 3s² 3p⁶ 3d² 4s². Shorthand (noble gas) notation: [Ar] 3d² 4s².
What is the noble gas configuration of titanium?
[Ar] 3d² 4s². The bracket stands for the Ar core electrons.
How many valence electrons does titanium have?
4 (2 outer s + 2 d electrons; 2 in the outermost shell).
How many unpaired electrons does titanium have?
2 in the ground state, following Hund’s rule. An atom with unpaired electrons is paramagnetic.
What is the electron configuration of Ti4+?
[Ne] 3s² 3p⁶ (18 electrons). Transition metal cations lose their outer s electrons before d electrons.
What is the electron configuration of Ti3+?
[Ar] 3d¹ (19 electrons). Transition metal cations lose their outer s electrons before d electrons.
