How would you account for the following?
The oxidising power of the following three oxo ions in the series follows the order :
`VO_(2)^(+)ltCr_(2)O_(7)^(2-)ltMnO_(4)^(-)`

Explanation

To account for the oxidizing power of the oxo ions \( VO_2^+ \), \( Cr_2O_7^{2-} \), and \( MnO_4^{-} \), we need to analyze the oxidation states of the central metal ions and their electronic configurations. This will help us understand their tendencies to gain electrons and thus their oxidizing power.

### Step-by-Step Solution:

1. **Determine the oxidation state of Vanadium in \( VO_2^+ \)**:
- The oxidation state of oxygen is \(-2\).
- For \( VO_2^+ \):
\[
