The properties of zirconium and hafnium atoms and ions are almost the ...
The atomic radius of the metal zirconium, Zr, (a period-5 transition element) is 159 pm and that of hafnium, Hf, (the corresponding period-6 element) is 156 pm. The ionic radius of Zr4+ is 79 pm and that of Hf4+ is 78 pm. The radii are very similar even though the number of electrons increases from 40 to 72 and the atomic mass increases from 91.22 to 178.49 g/mol.
This is due to Lanthanide contraction i.e. greater-than-expected decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, which results in smaller than otherwise expected ionic radii

Similarity in Properties of Zirconium and Hafnium
Almost Identical Ionic and Covalent Radii
- Zirconium and hafnium are two elements that belong to the same group in the periodic table, and they have similar atomic structures.
- Both zirconium and hafnium have almost identical ionic radii and covalent radii due to their similar electronic configurations.
- The similarity in atomic size allows these elements to exhibit analogous chemical behaviors and form similar compounds.
Explanation:
- Zirconium and hafnium are located in the same group of the periodic table, which means they have the same number of valence electrons.
- The atomic size of an element is determined by its electron configuration, and since zirconium and hafnium have the same number of electrons in their outermost shell, they have similar atomic radii.
- This similarity in atomic size results in almost identical ionic and covalent radii for zirconium and hafnium, leading to comparable chemical properties.
Conclusion
- The almost identical ionic and covalent radii of zirconium and hafnium contribute to their similar properties at the atomic and molecular levels.
- This similarity allows these elements to substitute for each other in various applications, such as in the production of nuclear reactors and certain alloys.
