Here's why:

* Silver (Ag) is a transition metal and typically forms a +1 cation (Ag⁺).

* Chlorine (Cl) is a nonmetal and typically forms a -1 anion (Cl⁻).

To create a neutral compound, the charges must balance. Therefore, one silver ion (Ag⁺) combines with one chloride ion (Cl⁻) to form AgCl, which is commonly known as silver chloride.
