Ferric chloride, also known as iron(III) chloride, has the chemical formula FeCl₃.

Here's the breakdown of its composition:

* Iron (Fe): This is the metal component, present in its +3 oxidation state (ferric).

* Chlorine (Cl): This is the non-metal component, present in its -1 oxidation state.

Therefore, each molecule of ferric chloride contains one iron atom and three chlorine atoms.
