Group 5 elements contains Vanadium, Niobium (Nb), tantalum (Ta) and dubnium[Db] whcih lies in d block elements.
Due to Lanthanide contraction Nb and Ta are called as Chemical twins means they are similar in properties .
Lanthanide Contraction :The steady derease of atomic or ionic radii from left to right in lanthanides is called as Lanthanide contraction.
Due to this : The crytsalline structure and other properties in lanthanides are very similar
