Draw the molecular structures of the following :
(a) Noble gas species which is isostructural with `BrO_(3)^(-)`
(b) Dibasic oxoacid of phosphorus

Explanation

### Step-by-Step Solution:

#### (a) Noble gas species which is isostructural with `BrO3^(-)`

1. **Identify the structure of `BrO3^(-)`:**
- Bromine (Br) has 7 valence electrons.
- In `BrO3^(-)`, bromine is the central atom bonded to three oxygen atoms.
- Two of the oxygen atoms are bonded with double bonds, and one oxygen is bonded with a single bond, carrying a negative charge.
