Question

Why The Size Of Hafmium And Zirconium are Same?????​

Answer 1

Answer:

Hi mate here is your answer..

Due to poor shielding effect of 4f electrons, the outer electrons experience a greater effective nuclear charge and the size of the element contracts. ... Due to lanthanide contraction, 5th and 6th-period transition series elements have similar sizes. Thus, the size of hafnium is almost similar to that of zirconium.
