First-Row Transition Metals
Elements from Sc to Zn that display variable oxidation states and form complex ions.
Complex Ion
A central metal ion surrounded by ligands bonded via coordinate covalent bonds.
Ligand Field Theory
Explanation of how d-orbitals split in energy when surrounded by ligands, leading to color.
Magnetic Properties
