Although zirconium belongs to 4d transition series and hafnium to 5d transition series even then they show similar physical and chemical properties because …….. .

A

both belong to d-block

B

both have same number of electrons

C

both have similar atomic radius

D

both belong to the same group of the periodic table

Text Solution

Verified by Experts

The correct Answer is:
C
Because of Lanthanide contraction both the element have similar atomic radius. Therefore, although zirconium belongs to 4d transition series and hafnium to 5d transition series even then they show similar physical and chemical properties.
