Excluding the inner transition elements, many of which are weird: Cr,Cu,Nb,Mo,Ru,Rh,Pd,Ag,Pt and Au.

They can all be rationalized by the unusual stability of a half or completelyfilled d subshell. That results in a predictable transfer of an s electron to the d subshell to make a half or completelyfilled subshell one element early for Cr, Cu, Mo, Ag and Au. The others (Nb,Ru,Rh,Pd,Pt) are just freaks, and you just have to remember them. W is also strange in *not* being strange. Like Cr and Mo, you'd *think* it would be d5,s1 but it's d4,s2. So W is also a freak.
