Why do ionic compounds generally have high melting points?

"Conductive when liquid-Ions are charged particles, but ionic compounds can only conduct. To allow electricity, heat or other energy forms to pass through electricity if their ions are free to move."

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)
