All of the following first row of the transition elements (3d-series) show the most common oxidation states.Mark the incorrect statement
Correct answer: C. Option C
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
a) Titanium (Ti): Titanium commonly exhibits oxidation states of +2 and +4. In its +2 oxidation state, it loses two electrons, and in its +4 oxidation state, it loses four electrons. Titanium is a transition metal with a strong affinity for oxygen, forming compounds like titanium dioxide (TiO2) in its +4 oxidation state. b) Vanadium (V): Vanadium is known for its various oxidation states, which include +2, +3, +4, and +5. Its +2 and +3 oxidation states are more common in compounds, while +4 and +5 oxidation states are less common. Vanadium compounds are used in catalysis and as components in batteries and steel alloys. c) Manganese (Mn): Manganese commonly displays oxidation states of +2, +3, +4, +6, and +7. Manganese compounds can range from pink (Mn2+) to dark purple (Mn7+). Manganese is an essential element for biological systems and is involved in various enzymatic reactions. d) Iron (Fe): Iron is another element with multiple oxidation states, including +2 and +3. It's often found in its +2 oxidation state in ferrous compounds and in its +3 oxidation state in ferric compounds. Iron is a crucial element in hemoglobin and myoglobin, which are responsible for transporting oxygen in blood and muscles.

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.
