Answer :
In general, covalent compounds are made up of two non-metals, whereas ionic compounds are made up of one non-metal and one metal.
CO2 is covalent since both are non-metals. CCl4 - yet another non-metal. Cl 2 - 2 non-metals are present. All covalent species are included in the set.
Ionic bonds, which are electrostatic forces of attraction between oppositely charged cations and anions, hold the individual ions that make up ionic compounds (also known as salts) together. Ionic compounds' characteristics provide some insight into the makeup of ionic bonding. Ionic solids typically have high melting and boiling temperatures, a crystalline structure, and a tendency to be rigid and brittle, all of which indicate that ionic bonding is highly strong.
