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

Explanation

Transition metals have a partially filled d−orbital. Therefore, the electronic configuration of transition elements is (n − 1)`d^(1-10) ns^(0-2)`.
The non-transition elements either do not have a d−orbital or have a fully filled d−orbital. Therefore, the electronic configuration of non-transition elements is `ns^(1-2)` or `ns^(2) np^(1-6)`.
