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

Explanation

Transition elements contain 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 d-subshell is completely filled and have `ns^(1-2) ` or `ns^(2) np ^(1-6)` in their outermost shell.
