Final answer:
Ionic and covalent compounds can be identified based on the types of atoms involved and the nature of the bonding.
Step-by-step explanation:
In order to identify whether a compound is covalent or ionic, we need to understand the nature of the bonding between the atoms.
Covalent compounds are formed when atoms share electrons, resulting in the formation of molecules. They are composed of non-metals or semi-metals with non-metals. Examples include NF3, IBr, and SO2.
Ionic compounds, on the other hand, are formed when there is a transfer of electrons between atoms, resulting in the formation of ions. They are composed of a metal with a non-metal. Examples include BaO, (NH4)2CO3, and CaF2.
