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

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

  • AX2 = linear = sp hybridization
  • AX3 = trigonal planar = sp2 hybridization
  • AX4 = tetrahedral = sp3 hybridization
  • AX5 = trigonal bipyramidal = sp3d hybridization
  • AX6 = octahedral = sp3d2 hybridization
