SOLVED: 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 -450-500-550600550-700"750800Using this diagram, answer the following questions.How many unpaired d electron spins does the cobalt atom have?paramagneticIs the complex paramagnetic or diamagnetic?diamagneticblue or greenred or violetPredict the color of the complex:orange or yell

SOLVED: The energies of the valence d orbitals on the cobalt atom in the tetrahedral [CoBr4]2- complex are split according to the electron box level diagram below. (Note: the d orbitals are labeled with just their subscript, to make the labels easier to read)Complete the diagram by adding the correct number of electrons to each orbital:energy2
