Goldschmidt radii of the elements were in fact the ones listed in Table 1.4 as ‘metallic radii’
and used in the discussion of the periodicity of atomic radius (Section 1.9). The essential features
of that discussion to bear in mind now, with ‘atomic radius’ interpreted as Goldschmidtcorrected
metallic radius in the case of metallic elements, are that metallic radii generally increase
down a group and decrease from left to right across a period.
