When certain strong-field ligand forms an octahedral complex with Co2+ cation, the energies of the valence d orbitals on the cobalt atom are split according to this electron box diagram: energy in kJlmol -350 -400 -450 -500 -550 600 550 -700 "750 800 Using this diagram, answer the following questions. How many unpaired d electron spins does the cobalt atom have? paramagnetic Is the complex paramagnetic or diamagnetic? diamagnetic blue or green red or violet Predict the color of the complex: orange or yellow white or transparent
