WebSolution Verified by Toppr The steady decrease in the size of lanthanide ions with the increase in atomic number is called lanthanide contraction. Consequences: There is not regular trend in ionization potential in the group due to lanthanide contraction. Similarity of 2nd and 3rd transition group Video Explanation WebIn p-block elements, the first member of each group differs from the other elements of the corresponding group. The following factors are responsible for this anomalous behaviour. 1. Small size of the first member. 2. High ionisation enthalpy and high electronegativity. 3. Absence of d orbitals in their valance shell. earbuds flesh color
