Calculate the oxidation number of all the atoms in the following species.
`BrF_(3)`

Explanation

To calculate the oxidation number of all the atoms in the species \( \text{BrF}_3 \), we can follow these steps:

### Step 1: Identify the elements in the compound
The compound \( \text{BrF}_3 \) contains two different elements: bromine (Br) and fluorine (F).

### Step 2: Determine the oxidation number of fluorine
Fluorine is the most electronegative element in the periodic table. It always has an oxidation number of \(-1\) in compounds. Therefore, for each fluorine atom in \( \text{BrF}_3 \):
- Oxidation number of F = \(-1\)
