The total number of transition elements is:
Correct answer: A. 58
- A. 58
- B. 48
- C. 30
- D. 25
Explanation
This is a factual recall question. There are 58 transition metals in the periodic table of elements, of which 30 are outer transition elements (d-block) and 28 are inner transition elements (f-block). Therefore option A is correct. (Source: FTBB book 2 page 64)

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.
