**radii**of the period-6 transition metals are smaller than would be expected if there were no lanthanides, and are in fact very similar to the**radii**of the period-5 ... 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 ... The increase in mass and the unchanged**radii**lead to a steep increase in density from 6.51 to 13.35 g/cm3 ...Metallic Bond - Metallic Radius

**radii**to the values the atoms would have if they were 12-coordinated ... Since metallic**radii**are always biggest for the highest coordination number, correction for less dense coordinations involves dividing by x, where 0 < x < 1 ... The**radii**follow general periodic trends they decrease across the period due to increase in the effective nuclear charge, which is not offset by the increased number of valence ...Platonic Solid - Geometric Properties -
