Among AgCl and Agl, which is more covalent?

Explanation

To determine which compound, AgCl or AgI, is more covalent, we can apply Fajan's rules. Here's a step-by-step solution:

### Step 1: Understand Fajan's Rules
Fajan's rules help predict whether a bond is more ionic or covalent based on the sizes of the ions involved. According to these rules, the covalent character of a bond increases when:
- The cation is small.
- The anion is large.
