The hybridization uses first #s# orbitals, then #p# orbitals, and finally #d# orbitals.

We can classify the electron geometries according to the #"AX"_n# system, and the total number of orbitals used is equal to #n#.

  • #"AX"_2# = linear = #sp# hybridization
  • #"AX"_3# = trigonal planar = #sp^2# hybridization
  • #"AX"_4# = tetrahedral = #sp^3# hybridization
  • #"AX"_5# = trigonal bipyramidal = #sp^3d# hybridization
  • #"AX"_6# = octahedral = #sp^3d^2# hybridization
