Hutchings, editor, Catalysis by Gold (Catalytic Science Series — Vol. 6), Imperial College Press, →ISBN, “5. Physical Properties of Gold and Adjacent Elements [§] 1. Bulk properties”, page 30:Gold crystallises in the face-centred cubic (fcc) habit, its lattice constant being fractionally smaller than that of silver (Tables 2.1 and 2.2.); in compounds and complexes, Au$^I$ is smaller than Ag$^I$. This is in consequence of the relativistic contraction of the 6s level, and it is expected that it will be even greater with the 7s level; indeed the size of the next element of Group 11 (röntgenium) has been calculated to be no larger than that of copper.

Röntgenium”, page 465:Possibility of Rg to form simple monovalent compounds and predominance of relativistic effects on its electron shells made this element an attractive object of theoretical investigations.
