The general electronic configuration of 3d series of transition elements is:
Correct answer: A. [Ar](n-1)d1-10ns1-2
- A. [Ar](n-1)d1-10ns1-2
- B. [Ar](n-1)d1-10ns2
- C. [Ar](n-1)d1-2ns1-2
- D. [Ar](n-2)d1-2ns1-2
Explanation
d-block (outer) transition elements are those in which d-subshell of penultimate shell (inner to valence shell) is in process of completion. So general electronic configuration of 3d series is (n-1) d1-10ns1-2

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
