Why do inert gases have larger values of atomic radius?

Explanation

### Step-by-Step Solution:

1. **Understanding Atomic Radius**:
- The atomic radius is defined as the distance from the nucleus of an atom to the outermost shell of electrons. It can vary based on the type of bonding and the state of the element.

2. **Trends in Atomic Radius**:
- Generally, as you move from left to right across a period in the periodic table, the atomic radius decreases. This is due to the increase in nuclear charge, which pulls the electrons closer to the nucleus.
