Part of the giant ionic lattice structure of sodium fluoride is shown in Figure 1.

Figure 1: A ball-and-stick model of a giant ionic lattice structure of sodium fluoride, showing a regular three-dimensional arrangement of alternating smaller green spheres representing sodium ions and larger yellow-green spheres representing fluoride ions connected by grey sticks representing ionic bonds.

Sodium fluoride has a melting point of 993∘C993^{\circ}\text{C}993∘C.

Explain why sodium fluoride has a high melting point.
