The ratio of the density of tantalum to that of niobium is 1 .94 , which is nearly identical to the 1.95 ratio of their atomic weights. How this similarity is a result of the lanthanide contraction has to be explained. Concept Introduction: Lanthanide contraction: The poor shielding of 4f orbital on nuclear charge results the increasing the attraction of 6s electrons towards the nucleus, it causes the atomic size reduction.
