Answer
KBr, MgI₂, and FeF₃
Step-by-step explanation
Ionic compounds consist of oppositely charged ions that are held together by ionic bonds.
Metals generally lose electrons to complete their octet while non-metals gain electrons to complete their octet. Metals and non-metals generally react to form ionic compounds.
Hence, out of the given compounds, the following are examples of ionic compounds: KBr, MgI₂, and FeF₃
