web.chem.ucsb.eduThe lanthanide elements are located just before the 5d transition metals. The lanthanide contraction is the steady decrease in the atomic radii of the lanthanide elements when going from left to right across the periodic table. As a result of the lanthanide contraction, the sizes

www.york.ac.ukradii of the lanthanides (approximately 25%). This is known as the lanthanide contraction. With respect to the transition metals the result is that the radii of the 2nd and 3rd row transition metals are very similar. E.g. Co(III) (0.55), Rh(III) (0.67), Ir(III) (0.68). This has repercussions in metal-ligand bonding and hence chemical properties.
