Due to lanthanoid contraction Z r and H F has similar atomic and ionic radii.

Q. $Z r (Z = 40)$ and $H f (Z = 72)$ have similar atomic and ionic radii because of

both belong to same group

diagonal relationship

lanthanide contraction

having similar chemical properties

Due to lanthanoid contraction $Z r$ and $H F$ has similar atomic and ionic radii.
