Identify the atoms in each of the following compounds which do not obey the octet rule:
`NH_3`

Explanation

To identify the atoms in the compound `NH₃` (ammonia) that do not obey the octet rule, we can follow these steps:

### Step 1: Understand the Octet Rule
The octet rule states that atoms tend to form bonds in such a way that they each have eight electrons in their valence shell, achieving a stable electron configuration similar to that of noble gases. However, there are exceptions to this rule.

### Step 2: Identify the Atoms in `NH₃`
In ammonia (NH₃), we have:
- Nitrogen (N)
