Potassium chloride is an ionic compound. The bond holding the atoms together is known as a ionic bond. The bonds in this lattice all have to be broken to melt the compound.
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.
Iodine, at p=p0,Boiling point 457.4 K,  184.3 °C(So I don't know if you'd call this high or low? compared with what?)However the difference with melting point of Iodine (386.85 K,  113.7 °C) is remarkably small (< 71oC) and the solid is quite vaporous far below its boiling point (Triple point 386.65K (113.5oC), 12.07 kPa, just below melting point).
Because it is a non metal and does not conduct electricity
High melting point
pottassium is a drug that makes high which is fun its like Viagra
The melting teperature is relatively high
The melting point of potassium chloride is 790 °C.

No , table salt (sodium chloride) has a melting point of 801°C
The melting point of sodium chloride is 801 0C.
NaCl (sodium chloride)
The melting point of sodium chloride ( NaCl ) is 801 °C, 1074 K, 1474 °F.
Sodium chloride is a ionic compound. Generally they have high melting points.
because it has high melting/dissolving point.
No, it is an ionic salt like sodium chloride, having very high melting and boiling points.
Sublimation - on gentle heating ammonium chloride will sublime. Sodium Chloride does not and has a high melting point.
Table Salt (Sodium Chloride or NaCl) melts at a temperature of 801° C (1474° F) and is able to conduct electricity in its "molten" state.
