In what way is the electronic configuration of the transition elements different from that of the non transition elements?

Explanation

Transition elements contains incompletely filled d-subshell, i.e., their electronic configuration is `(n-1)d^(1-10)ns^(0-2)` whereas non-transition elements have no d-subshell or their subshell is completely filled and have `ns^(1-2)` or `ns^(2)` `np^(1-6)` in their outermost shelt.
