Answer: The crystal structure of ionic compounds is strong and rigid. It takes a lot of energy to break all those ionic bonds. As a result, ionic compounds are solids with high melting and boiling points.
Ionic compounds are solids with high melting and boiling points.
Explanation:
The crystal structure of these ionic compounds are very strong and rigid. It will take a lot of energy to break all of those ionic bonds. The super strong bonds between their oppositely charged ions pre-lock them into postion in their crystal.
