The oxidation number of oxygen in `F_(2)O` and `H_(2)O_(2)` are ......... and ......... respectively.

Explanation

To determine the oxidation numbers of oxygen in the compounds \( F_2O \) and \( H_2O_2 \), we can follow these steps:

### Step 1: Determine the oxidation number of oxygen in \( F_2O \)

1. **Identify the known oxidation state of fluorine**: Fluorine (F) is the most electronegative element and has an oxidation number of \(-1\).
2. **Set up the equation**: In \( F_2O \), there are two fluorine atoms. Let the oxidation number of oxygen be \( x \). The equation based on the overall charge being zero is:
\[
2(-1) + x = 0
