Elements of 3d-series generally show which of the following stable oxidation states
Correct answer: B. +2, +3
- A. +1, +2
- B. +2, +3
- C. +4, +5
- D. +6, +7
Explanation
Based on the typical behavior of elements in the 3d-series of the periodic table, the correct option for stable oxidation states is: Elements in the 3d-series of the periodic table, also known as the transition metals, frequently exhibit stable oxidation states of +2 and +3. These elements have unique electron configurations that make these oxidation states particularly stable and common in their chemical reactions.

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.
