Why `Zr` and `Hf` or `Nb` and `Ta` exhibit similar properties?
Or Zirconium (atomic number 40 and atomic number 72) occur together in minerals and they exhibit similar properties. Give reasons.

Text Solution

Verified by Experts

Due to lanthanoid contraction,`Hf(Z= 72)` has size similar to that Zr `(Z = 40)` . Hence, their properties are similar and therefore, occur together. For the same reason, Nb and Ta have similar size and hence similar properties.
