Hafnium ground state electronic configuration

For practical purposes, then, the third transition series begins with hafnium, having the ground state outer electron configuration 6s25d2, and embraces the elements Ta, W, Re, Os, Ir, Pt, and Au, all of which have partially filled 5d shells in one or more chemically important oxidation states as well as (except Au) in the neutral atom.
