Practice question

Given: What is the maximum oxidation state exhibited by vanadium in the 3d series? These values define the system as per NCERT data. Formula: Vanadium (V, Z = 23) exhibits oxidation states from +2 to +5, with +5 being the maximum, as seen in VO₂^+ .. This is standard NCERT relation. Substitution & Calculation: Substituting values and simplifying step by step as per NCERT method. Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
