Answers
The compounds which are made up of ions are called as ionic compounds. In an ionic compound,the positively charged ion(cation) and negatively charged ion(anion) are held together by the strong electrostatic forces of attraction. The forces which hold them together are called as ionic bonds or electrovalent bonds.
Explanation:
Properties of Ionic Compounds
Ionic Compounds have high boiling and melting points as they’re very strong and require a lot of energy to break.
The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions.
Ionic compounds form crystals.
These compounds are brittle and break into small pieces easily.
Electrovalent compounds usually dissolve in water and are insoluble in solvents like oil, petrol, kerosene, etc.
Ionic compounds do not conduct electricity in a solid-state but they do conduct electricity in the molten state.
In comparison to molecular compounds, ionic compounds have higher enthalpies of fusion and vaporization
