Here's why:

* Ionic Compounds: Silver chloride is an ionic compound, meaning it's formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).

* Charges: Silver (Ag) has a +1 charge, and chloride (Cl) has a -1 charge.

* Balancing: To form a neutral compound, one silver ion (Ag+) combines with one chloride ion (Cl-).
