<P> In physics, the definition of a noble metal is most strict . It requires that the d bands of the electronic structure be filled . From this perspective, only copper, silver and gold are noble metals, as all d - like bands are filled and do not cross the Fermi level . However, d - hybridized bands do cross the Fermi level to a small extent . In the case of platinum, two d bands cross the Fermi level, changing its chemical behaviour such that it can function as a catalyst . The difference in reactivity can easily be seen during the preparation of clean metal surfaces in an ultra-high vacuum: surfaces of "physically defined" noble metals (e.g., gold) are easy to clean and keep clean for a long time, while those of platinum or palladium, for example, are covered by carbon monoxide very quickly . </P> <P> Metallic elements, including metalloids (metals usually considered noble bolded, predictions for superheavy elements italicised): </P> <Table> <Tr> <Th> Element </Th> <Th> Atomic number </Th> <Th> Group </Th> <Th> Period </Th> <Th> Reaction </Th> <Th> Potential </Th> <Th> Electron configuration </Th> </Tr> <Tr> <Td> Copernicium </Td> <Td> 112 </Td> <Td> 12 </Td> <Td> 7 </Td> <Td> Cn + 2 e → Cn </Td> <Td> 2.1 V </Td> <Td> (Rn) 5f 6d 7s </Td> </Tr> <Tr> <Td> Roentgenium </Td> <Td> 111 </Td> <Td> 11 </Td> <Td> 7 </Td> <Td> Rg + 3 e → Rg </Td> <Td> 1.9 V </Td> <Td> (Rn) 5f 6d 7s </Td> </Tr> <Tr> <Td> Darmstadtium </Td> <Td> 110 </Td> <Td> 10 </Td> <Td> 7 </Td> <Td> Ds + 2 e → Ds </Td> <Td> 1.7 V </Td> <Td> (Rn) 5f 6d 7s </Td> </Tr> <Tr> <Td> Gold </Td> <Td> 79 </Td> <Td> 11 </Td> <Td> 6 </Td> <Td> Au + 3 e → Au </Td> <Td> 1.5 V </Td> <Td> (Xe) 4f 5d 6s </Td> </Tr> <Tr> <Td> Astatine </Td> <Td> 85 </Td> <Td> 17 </Td> <Td> 6 </Td> <Td> At + e → At </Td> <Td> 1.0 V </Td> <Td> (Xe) 4f 5d 6s 6p </Td> </Tr> <Tr> <Td> Platinum </Td> <Td> 78 </Td> <Td> 10 </Td> <Td> 6 </Td> <Td> PtO + 2 H + 2 e → Pt + H O </Td> <Td> 0.98 V </Td> <Td> (Xe) 4f 5d 6s </Td> </Tr> <Tr> <Td> Palladium </Td> <Td> 46 </Td> <Td> 10 </Td> <Td> 5 </Td> <Td> Pd + 2 e → Pd </Td> <Td> 0.915 V </Td> <Td> (Kr) 4d </Td> </Tr> <Tr> <Td> Flerovium </Td> <Td> 114 </Td> <Td> 14 </Td> <Td> 7 </Td> <Td> Fl + 2 e → Fl </Td> <Td> 0.9 V </Td> <Td> (Rn) 5f 6d 7s 7p </Td> </Tr> <Tr> <Td> Meitnerium </Td> <Td> 109 </Td> <Td> 9 </Td> <Td> 7 </Td> <Td> Mt + 3 e → Mt </Td> <Td> 0.8 V </Td> <Td> (Rn) 5f 6d 7s </Td> </Tr> <Tr> <Td> Silver </Td> <Td> 47 </Td> <Td> 11 </Td> <Td> 5 </Td> <Td> Ag + e → Ag </Td> <Td> 0.7993 V </Td> <Td> (Kr) 4d 5s </Td> </Tr> <Tr> <Td> Mercury </Td> <Td> 80 </Td> <Td> 12 </Td> <Td> 6 </Td> <Td> Hg + 2 e → 2 Hg </Td> <Td> 0.7925 V </Td> <Td> (Xe) 4f 5d 6s </Td> </Tr> <Tr> <Td> Iridium </Td> <Td> 77 </Td> <Td> 9 </Td> <Td> 6 </Td> <Td> IrO + 4 H + 4 e → Ir + 2 H O </Td> <Td> 0.73 V </Td> <Td> (Xe) 4f 5d 6s </Td> </Tr> <Tr> <Td> Osmium </Td> <Td> 76 </Td> <Td> 8 </Td> <Td> 6 </Td> <Td> OsO + 4 H + 4 e → Os + 2 H O </Td> <Td> 0.65 V </Td> <Td> (Xe) 4f 5d 6s </Td> </Tr> <Tr> <Td> Polonium </Td> <Td> 84 </Td> <Td> 16 </Td> <Td> 6 </Td> <Td> Po + 2 e → Po </Td> <Td> 0.6 V </Td> <Td> (Xe) 4f 5d 6s 6p </Td> </Tr> <Tr> <Td> Nihonium </Td> <Td> 113 </Td> <Td> 13 </Td> <Td> 7 </Td> <Td> Nh + e → Nh </Td> <Td> 0.6 V </Td> <Td> (Rn) 5f 6d 7s 7p </Td> </Tr> <Tr> <Td> Rhodium </Td> <Td> 45 </Td> <Td> 9 </Td> <Td> 5 </Td> <Td> Rh + 2 e → Rh </Td> <Td> 0.60 V </Td> <Td> (Kr) 4d 5s </Td> </Tr> <Tr> <Td> Ruthenium </Td> <Td> 44 </Td> <Td> 8 </Td> <Td> 5 </Td> <Td> Ru + 3 e → Ru </Td> <Td> 0.60 V </Td> <Td> (Kr) 4d 5s </Td> </Tr> <Tr> <Td> Tellurium </Td> <Td> 52 </Td> <Td> 16 </Td> <Td> 5 </Td> <Td> TeO + 4 H + 4 e → Te + 2 H O </Td> <Td> 0.57 V </Td> <Td> (Kr) 4d 5s 5p </Td> </Tr> <Tr> <Td> Hassium </Td> <Td> 108 </Td> <Td> 8 </Td> <Td> 7 </Td> <Td> Hs + 4 e → Hs </Td> <Td> 0.4 V </Td> <Td> (Rn) 5f 6d 7s </Td> </Tr> <Tr> <Td> Copper </Td> <Td> 29 </Td> <Td> 11 </Td> <Td> </Td> <Td> Cu + 2 e → Cu </Td> <Td> 0.339 V </Td> <Td> (Ar) 3d 4s </Td> </Tr> <Tr> <Td> Bismuth </Td> <Td> 83 </Td> <Td> 15 </Td> <Td> 6 </Td> <Td> Bi + 3 e → Bi </Td> <Td> 0.308 V </Td> <Td> (Xe) 4f 5d 6s 6p </Td> </Tr> <Tr> <Td> Technetium </Td> <Td> 43 </Td> <Td> 7 </Td> <Td> 5 </Td> <Td> TcO + 4 H + 4 e → Tc + 2 H O </Td> <Td> 0.272 V </Td> <Td> (Kr) 4d 5s </Td> </Tr> <Tr> <Td> Rhenium </Td> <Td> 75 </Td> <Td> 7 </Td> <Td> 6 </Td> <Td> ReO + 4 H + 4 e → Re + 2 H O </Td> <Td> 0.276 V </Td> <Td> (Xe) 4f 5d 6s </Td> </Tr> <Tr> <Td> Arsenic </Td> <Td> 33 </Td> <Td> 15 </Td> <Td> </Td> <Td> As O + 12 H + 12 e → 4 As + 6 H O </Td> <Td> 0.24 V </Td> <Td> (Ar) 3d 4s 4p </Td> </Tr> <Tr> <Td> Antimony </Td> <Td> 51 </Td> <Td> 15 </Td> <Td> 5 </Td> <Td> Sb O + 6 H + 6 e → 2 Sb + 3 H O </Td> <Td> 0.147 V </Td> <Td> (Kr) 4d 5s 5p </Td> </Tr> <Tr> <Td> Livermorium </Td> <Td> 116 </Td> <Td> 16 </Td> <Td> 7 </Td> <Td> Lv + 2 e → Lv </Td> <Td> 0.1 V </Td> <Td> (Rn) 5f 6d 7s 7p </Td> </Tr> <Tr> <Td> Bohrium </Td> <Td> 107 </Td> <Td> 7 </Td> <Td> 7 </Td> <Td> Bh + 5 e → Bh </Td> <Td> 0.1 V </Td> <Td> (Rn) 5f 6d 7s </Td> </Tr> </Table> <Tr> <Th> Element </Th> <Th> Atomic number </Th> <Th> Group </Th> <Th> Period </Th> <Th> Reaction </Th> <Th> Potential </Th> <Th> Electron configuration </Th> </Tr>
