The hybridization also controls the oxidation locus (valence tautomerism), which is . We can find the hybridization of an atom in a molecule by either looking at the types of bonds surrounding the atom or by calculating its steric number. To describe the five bonding orbitals in a trigonal bipyramidal arrangement, we must use five of the valence shell atomic orbitals (the s orbital, the three p orbitals, and one of the d orbitals), which gives five sp 3 d hybrid orbitals.With an octahedral arrangement of six hybrid orbitals, we must use six valence shell atomic orbitals (the s orbital, the .
