The video tutorial explains the differences between Lanthanides and Actinides, focusing on their positions in the periodic table, orbital filling, atomic numbers, oxidation states, paramagnetic properties, radioactivity, oxocations, compounds, binding energy, and shielding effects. Lanthanides fill 4F-orbitals and have atomic numbers 57-71, while Actinides fill 5F-orbitals with atomic numbers 89-103. Lanthanides show a maximum oxidation state of ±4, whereas Actinides exhibit variable states up to ±7. Lanthanides are mostly non-radioactive, unlike the radioactive Actinides. The video also covers the basicity of compounds and the effectiveness of shielding effects.
