Subject: Periodic table-electron configuration of palladium

Gentlemen;

I am a retired Civil Engineer doing research, (as a hobbie), on the periodic table.  The best 
source of data I have located shows the electron configuration for the element Palladium, # 46, 
as follows.

               1           2              3                 4
               s         s   p        s   p   d        s   p   d   f  

               2         2   6        2   6   10       2   6   10  -

It has been my understanding that it was not possible to have an element with more than 8 
electrons in it's outermost shell.  If this configuration is correct, this element has 18.  Is 
this an exception to the rule, a misstatement of configuration or is there another explanation 
for this anomaly ?

I understand that I can have questions such as this answered by your service.  I would be 
grateful if you could enlighten me on this matter.

Yours truly;
