Octahedral crystal-field splitting diagram → d-orbital electrons
▪ charge = +3: means that it lost 3 electrons:
• subtract the electrons from the highest numbered orbital or higher energy orbital: 4s first then 3d
•V3+: [Ar] 3d2
Construct the octahedral crystal-field splitting diagram for the metal in each species.
