Potassium iodide, like salts in general, has a high melting point. It does not melt easily when heated.
The melting teperature is relatively high
The melting point of potassium chloride is 790 °C.
low melting point
Potassium does have a high melting point, it is 63.7 degrees Celsius.

NaI has ions and has strong electrostatic force of attraction, hence high melting point. Naphthalene has weak van der Waals forces of attraction between the molecules and hence have low melting point.

high melting point
High melting point
it has a low melting point
Potassium chloride is an ionic compound. The bond holding the atoms together is known as ionic bond. Strictly speaking it is NOT a discrete molecule of K + Cl- but a crystal lattice consisting of each K+ surrounded by Cl- ions and vice versa. The bonds in this lattice all have to be broken to melt the compound. There is a strong electrostatic force of attraction between the chloride ions and the potassium ions. A large amount of heat energy has to be applied to break the strong bond holding the atoms, resulting in the compound having a high melting point.
All metals have different melting points but they are all high
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
