This page shows the electron configurations of the neutral gaseous atoms in their ground states. For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell. For phosphorus (element 15) as an example, the concise form is [Ne] 3s 2 3p 3.
Ti 2 2 - 23 V 2 3 - 24 Cr 1 5 - 25 Mn 2 5 - 26 Fe 2 6 - 27 Co 2 7 - 28 Ni 2 8 - 29 Cu 1 ... Note that these electron configurations are given for neutral atoms in the ...
For example, the electron configuration of the titanium ground state can be written as either [Ar] 4s 2 3d 2 or [Ar] 3d 2 4s 2. The first notation follows the order based on the Madelung rule for the configurations of neutral atoms; 4s is filled before 3d in the sequence Ar, K, Ca, Sc, Ti.
Electron configuration 3d 2 4s 2: ... Also known is Ti 2 O 3, with the corundum structure, and TiO, with the rock salt structure, although often nonstoichiometric.
Electron configurations of the group 4 elements Z Element Electron configuration 22: Ti, titanium: 2, 8, 10, 2
For example, the Ti 2+ ion has the ground-state configuration [Ar]3d 2 [8] with a d electron count of 2, even though the total number of electrons is the same as the neutral calcium atom which is [Ar]4s 2.
The lightest atom that requires the second rule to determine the ground state term is titanium (Ti, Z = 22) with electron configuration 1s 2 2s 2 2p 6 3s 2 3p 6 3d 2 4s 2. In this case the open shell is 3d 2 and the allowed terms include three singlets ( 1 S, 1 D, and 1 G) and two triplets ( 3 P and 3 F).
