Please tell me what the electron configuration of palladium means. It's 
listed as [Kr]4d^10 5s^0. How can this be? I learned that 
valence electrons can only be in the s and p sublevels (and number only up 
to 8), yet they seem to 
be either nonexistent or in the 4d sublevel (and number 10). Can it be in 
d? Or, if it is 
5s, how can there be zero electrons in the valence? Why is it zero, 
instead of simply not shown? As palladium is not a noble gas, I know it 
must have valence electrons, but I can't understand just how. No other 
elements have this unique "zero" feature. Previous questions on this don't 
clear this up for me.
