The IUPAC nomenclature of an element with electronic configuration Rn 5 f 14 6 d 1 7 s 2 is

Step-by-step solution

IUPAC nomenclature has been recommended for all the elements with Z > 100 . It was decided by IUPAC that the names of elements beyond atomic number 100 should use Latin words for their numbers. The names of these elements are derived from their numerical roots.
