Answer:
The characteristic properties are hard and brittle solids having high melting and boiling point
Step-by-step explanation:
Ionic compounds are the type of chemical compounds that are formed by ionic bonding. An ionic compound is composed of two oppositely charged ions that are held together by electrostatic forces of attraction.
They are solids at room temperature and usually have a crystalline structure and have high melting and boiling point. Ionic compounds are hard but also brittle.
