Question

Mention any other consequence of Lanthanide Contraction

Answer 1

Another consequence of lanthanide contraction is that it leads to the similarity in the chemical properties of the elements in the same group, even if they are not in the same period. For instance, due to the contraction, the atomic radii of elements like Hf (in period 6) and Zr (in period 4) are almost the same, and they exhibit similar chemical reactivity, ionization energies, and electronegativity values. Lanthanide contraction also contributes to the formation of sim ilar ions for elements in the same group
