which characteristic(s) makes ionic compounds useful as a building material?\no low melting and boiling points\no hardness and brittleness\no inability to conduct electricity\no inability to dissolve in water
Answer
Brief Explanations:
Ionic compounds have strong ionic bonds which give them hardness. Their brittleness can also be utilized in building materials in certain applications. Low melting/boiling points would make them unsuitable for construction. Their conductivity and solubility properties are not what make them useful as building materials.
Answer:
hardness and brittleness
