The oxidation state of transition elements is usual
Correct answer: A. Variable
- A. Variable
- B. Constant
- C. Single
- D. infinite
Explanation
Because their valence electrons are in two separate sets of orbitals, (n-1)d and ns, these elements have varying oxidation states. Because the energy difference between these orbitals is so small, both energy levels can be utilised to build bonds. As a result, the oxidation states of transition elements vary.

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.
