The total number of transition elements are?
Correct answer: A. 48
- A. 48
- B. 32
- C. 58
- D. 28
Explanation
There are "38" d-block elements that show variable oxidation states and have partially filled d-orbitals hence the answer is A.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
