The electron configuration of gallium is 1s22s22p63s23p64s23d104p1 The shorter version is [Ar]4s23d104p1
All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
The condensed electron configuration of polonium is [Xe] 6s^2 4f^14 5d^10 6p^4.
