Which of the following compounds is a common oxidation state of vanadium? (2022)

Which of the following compounds is a common oxidation state of vanadium? (2022)

Step 1: Understand what oxidation states are. Oxidation states indicate the degree of oxidation of an atom in a compound.
Step 2: Identify the oxidation states of vanadium in the given compounds.
Step 3: Look at V2O5. Each vanadium (V) atom has an oxidation state of +5.
Step 4: Look at VO. The oxidation state of vanadium in this compound is +2.
Step 5: Look at V2O3. The oxidation state of vanadium here is +3.
Step 6: Conclude that all the listed compounds represent common oxidation states of vanadium: +5 in V2O5, +2 in VO, and +3 in V2O3.
