d and f BLOCK ELEMENTS Quiz

• s-d electronic transitions
• Charge transfer transitions only
• d-d electronic transitions absorbing specific wavelengths of visible light.
• Reflection of all visible wavelengths

• It shows multiple oxidation states.
• It forms colored compounds.
• It has an incomplete d-subshell in its ground state.
• It is paramagnetic.

• Lanthanoids are radioactive.
• Actinoids predominantly show the +3 state.
• Actinoids exhibit a wider range of oxidation states compared to Lanthanoids.
• Lanthanoids have simpler electronic configurations.

• It results in a half-filled f subshell.
• It is the only oxidation state they can exhibit.
• It allows them to achieve a stable electronic configuration similar to the preceding noble gas.
• It makes them paramagnetic.

• Ligands fill the d-orbitals completely.
• Ligands remove all d-electrons.
• Ligands cause the d-orbitals to split into different energy levels.
• Ligands have no effect on d-orbitals.
