Why zero group element do not form compound under ordinary conditions?

Explanation

### Step-by-Step Solution:

1. **Understanding Noble Gases**: Noble gases, also known as Group 18 elements or zero group elements, include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). They are characterized by their complete valence electron shells.

2. **Electronic Configuration**: The general electronic configuration of noble gases (except Helium) is \( ns^2 np^6 \). Helium has a configuration of \( 1s^2 \). This means that their outermost shells are fully filled, making them very stable.

3. **Stability of Electronic Configuration**: The fully filled electronic configuration leads to a state of stability. Noble gases do not tend to gain or lose electrons because doing so would disturb this stable configuration.
