d and f BLOCK ELEMENTS Quiz

• Solvents are always colorless.
• The metal changes oxidation state.
• The ligand environment and crystal field splitting can differ between states.
• Temperature affects the d-orbitals directly.

• Ligands are always spherical.
• Metal ions force ligands into specific positions.
• The arrangement of ligands minimizes repulsion and maximizes ligand field stabilization energy.
• Geometries are random.

• It makes them highly reactive in their elemental form.
• It prevents them from forming bonds.
• It allows for variable oxidation states and the formation of temporary bonds with reactants.
• It makes them good electrical insulators.

• Large differences in atomic size
• Different crystal structures
• Similar atomic sizes and the ability to substitute for each other in crystal lattices.
• Ionic bonding between metals

• They always form high-spin complexes.
• They have no effect on electron pairing.
• They tend to cause pairing of electrons, forming a low-spin complex.
• They fill the eg orbitals first.
