    Hafnium is chemically similar to irconium. Both transition metals have similar electronic configurations and their ionic radii Zr 4 0.74 and Hf 4 0.75 and atomic radii irconium 1.45 and hafnium 1.44 are nearly identical because of the influence of the lanthanoid contraction.In fact the chemical behaviour of these two elements is more similar than for any other pair
