10 cards from this deck
Form stable ions with incomplete ddd-sublevel
Central metal ion bonded to ligands via coordinate bonds
Donate lone pairs of electrons to the metal ion
Electronic transitions in ddd-sublevel absorb visible light
Blue
Close energy levels of 4s4s4s and 3d3d3d orbitals
Provide lower activation energies, can change oxidation states
Iron (Fe)
3d54s13d^{5}4s^{1}3d54s1 (half-filled 3d3d3d provides stability)
3d104s13d^{10}4s^{1}3d104s1 (fully filled 3d3d3d is more stable)
