Electron configuration

As a result of the formation of the complex, the central ion often attains the electron configuration of the following noble gas in that the electron pairs of the ligands fill empty orbitals of the central ion:

example

Al3+1s22s22p6

+ 4 ligands = + 8 electrons

[Al(OH)4]1s22s22p63s23p6

Ar- Noble gas configuration: 1s22s22p63s23p6

example

Fe2+1s22s22p63s23p63d6

+ 6 ligands = + 12 electrons

[Fe(C.N)6]41s22s22p63s23p63d104s24p6

Kr- Noble gas configuration:1s22s22p63s23p63d104s24p6

example

Co3+1s22s22p63s23p63d6

+ 6 ligands = + 12 electrons

[Co(NH)6]3+1s22s22p63s23p63d104s24p6

Kr- Noble gas configuration:1s22s22p63s23p63d104s24p6
