The transition elements have a characteristic electronic configuration which can be represented as
A.(n – 2) s2p6d1–10 (n – 1) s2p6ns2
B.(n – 2) s2p6d1–10 (n – 1) s2p6d1 or 2 ns1
C.(n – 1)s2p6d10 ns2np6nd1–10
D.(n – 1) s2p6d1–10ns0–2✓ Correct
Explanation
The transition elements are those which have partially filled d orbitals. The general electronic configuration of transition elements is given by- 2 6 1 10 0 2 ( 1) n s p d ns Thus, the correct answer is (d).
