Choose the correct answer about transition elements:
Correct answer: C. Transition elements exhibit variable oxidation states
- A. Transition elements have low melting points
- B. Transition elements do not have catalytic activity
- C. Transition elements exhibit variable oxidation states
- D. Transition elements exhibit inert pair effect
Explanation
Transition elements exhibit variable oxidation states: This statement is correct. Transition elements typically have incompletely filled d-orbitals, allowing them to readily lose or gain electrons, leading to the ability to exhibit multiple oxidation states.

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.
