Single Choice
Although Zirconium belongs to 4d transition series and Hafnium to 5d transition series even then they show similar physical and chemical properties because:
Aboth belong to d-block
Bboth have same number of electrons
Cboth have similar atomic radius
Correct Answer
Dboth belong to the same group of the periodic table
Solution
Zirconium belongs to 4d transition series and Hafnium belongs to 5d transition series but they show similarity in physical and chemical properties because of similar atomic radius arising because of lanthanoid contraction
