Solution
In a giant ionic lattice, the ions are held together by very strong electrostatic forces of attraction that exist in all directions within the lattice. This means that the ions are very tightly bound to each other.
When we heat a substance, we are essentially providing it with energy. This energy is used to overcome the forces holding the particles (in this case, ions) together. The more energy required to overcome these forces, the higher the temperature needed, hence a higher melting point.
In the case of a giant ionic lattice, because the electrostatic forces of attraction are so strong, a large amount of energy is needed to overcome these forces and separate the ions from each other. This is why substances with a giant ionic lattice structure have very high melting points.
Therefore, the correct statement is: "A lot of energy is needed to overcome the electrostatic forces and separate the ions from each other."
