531 Transition Elements MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
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.

- A. S and p block
- B. D and f block
- C. S and f block
- D. None of these options are correct
Explanation: The location of transition elements is in between the s and p block of the periodic table. Transition elements are found in the d-block.
Correct answer: S and p block- A. Fe²⁺
- B. Mn4⁺
- C. Cr³⁺
- D. Cu²⁺
Explanation: The electron configuration of Fe²⁺ is [Ar] 3d⁶. In the 3d orbital, there are 4 unpaired electrons.
Correct answer: Fe²⁺- A. [Cr(NH3)5SO4]Cl
- B. [Co(NH2)4SO4]NO2
- C. [Cr(NH3)5Cl]SO4
- D. Both (A) and (C)
Explanation: BaCl2 gives white precipitate of BaSO4 with SO4 ions, so the complex must have SO4 ions in the ionization sphere.
