Anna stated that ionic compounds have high melting points and low boiling points. She said that this demonstrates that ionic compounds have strong bonds because a lot of energy is needed to break the electrical forces that hold the bonds together. Which statement best describes Anna’s error? A)Strong electrical forces will make ionic compounds have […]
