Question: what is the electron configuration of the complex co(nh3)6 3+?
Answer: In complex [Co (NH3)6]3+the type of hybridization is d2sp3 let us explain it, Co is in +3oxidation state with the configuration 3d6. In the presence of NH3 a strong ligand, the 3d electrons pair up leaving two d-orbitals empty. Hence, the hybridization is d2sp3 forming an inner orbital octahedral comlpex.
