First transition series starts with:
Correct answer: B. Sc
- A. Y
- B. Sc
- C. Zn
- D. Cd
Explanation
Sc (Scandium) is correct because the first transition series begins with scandium. This is because scandium has the electronic configuration [Ar] 3d^1 4s^2, marking the beginning of the filling of the 3d subshell in transition metals.

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.
