According with this discussion parts of my booklet "Gold electronic enigma, 1, 2 or 3" have been updated. 1st part to be updated: 2.Why they are noble? Noble metals are a particular case of transition metals. Those with relativistic contraction (i.e. full 5d-band), comprising the heavy group...

Or vice versa. In Al the population of d increases with pressure. "calculated pressure induced fcc-hcp phase transition in aluminum" by H.Dagistanli, Bitlis Eren Univ J Sci & Technol, ISSN 2146-7706, 3 (2013), 6-8

May I repeat, Nd for copper and silver, 1.99 and 1.03 resp. are low vs. other metals, e.g. Pd = 30.6 and comparable with Pb(0.99), Al(1.62), Cd(0.35) but not 0

Thanks Zz. In this case how you explain Nd for copper =1.99?

Here is a quotation from Wikipedia, noble metals Physics[edit] In physics, the definition of a noble metal is most strict. It requires that the d-bands of the electronic structure are filled. From this perspective, only copper, silver and gold are noble metals, as all d-like bands are filled and...

Here are some refs, to name few, discussing density of states at the Fermi level S.K.Bose in J.Phys.Condens. matter 21 (2009) p. 1- "Electron-phonon coupling... in 3d and 4d transition metals... etc" gives Nd 1.99 for Cu, 1.03 for Ag I.I.Mazin et al J.Phys.F: Met. Phys. 14 (1984) p 167-174...

I encounter contradictive informations about this issue which is supposed to define "real noble metals" is this statement correct at absolute zero or at any temperature? Does it include ds hybridizations?
