Answer : The correct options are, brittleness and high melting point
Explanation :
Ionic compound : Ionic compounds are the compounds which are formed when a metal cation bonded with non-metal anion. The metal cation and non-metal anion bonded with an electrostatic force of attraction.
The properties of ionic compounds are :
Ionic compounds are brittle and hard. They breaks easily into small pieces.
They have high melting point and boiling point.
They conduct electricity in liquid state not in solid state.
Hence, the brittleness and high melting point properties are the characteristic of ionic compounds.
