Explain why ionic substances have high melting points.

There are very strong electrostatic forces of attraction in all directions in a giant ionic lattice.Why does this result in a very high melting point?A lot of energy is needed to overcome the electrostatic forces and separate the electrons from each other.A lot of energy is needed to overcome the electrostatic forces and hold the ions together.A lot of energy is needed to overcome the electrostatic forces and separate the atoms from each other.A lot of energy is needed to overcome the electrostatic forces and separate the ions from each other.
