उत्तर
Similarities between the lanthanoid and actinoid: They have prominent oxidation states of +3 or they are electropositive or they both show magnetic properties.
Difference between the lanthanoid and actinoid: Lanthanoids are involved in filling of 4f orbitals while actinoids are involved in filling of 5f orbitals or binding energy of 4f orbitals is less than 5f orbitals
