In What way is the electronic configuration of the transition elements different from the of the non-transition elements?

Explanation

The transition elements involve the filling of d-orbitals while the representative elements involve the filling of s or p-orbitals. The general electronic configuration of transition elements is `(n-1) d^(1-10) ns^(1-2)` . On the other hand, the general electronic configuration of representative elements in `ns^(1-2) or ns^2np^(1-6)`. Thus, in representative elements, only the last shell is incomplete while in transition elements the last but one shell is also incomplete.
