which characteristic(s) makes ionic compounds useful as a building material? low melting and boiling points hardness and brittleness inability to conduct electricity inability to dissolve in water

Answer

Brief Explanations:

Ionic compounds have strong ionic bonds. Their hardness can be beneficial for building - they can withstand pressure. Brittleness can be a factor in some building applications too. Low melting and boiling points would make them unsuitable for building as they would change state easily. Inability to conduct electricity and dissolve in water are not the main characteristics that make them useful as building materials.

Answer:

hardness and brittleness
