The energy between the sets of sigma orbits is called the crystal field energy, Delta when Delta is large sigma energies are placed in the lower energy sigma orbitals and are paired (low-spin complex). When Delta is small, electrons are placed in below the higher and lower energy orbitals before any pairing occurs (high-spin complex). The complex ion is a high-spin complex and absorbes light wavelength greater than 7.70 Time 10 2 . How many unpaired electrons will be present in the complex? Express your answer numerically as an integer. If the ligands are submitted with CN- ligands to from [Co(CN)4]3-, the complex becomes low spin and absorbs light at 2.90 times 10 2 . How many unpaired electrons are in [Co(CN)4] ? Express your answer numerically as an integer. What is the wavelength of light absorbed by [Co(NH4) ] ?
