NaCl is an ionic compound formed between Sodium and Chlorine by transfer of electrons.
Since, they are ionic, they are held by very strong electrostatic forces and hence, the bonding is quite strong.
Therefore, a large amount of heat has to be supplied to melt it.
No, it is very low. Argon has a melting point of −189.3°C
Potassium does have a high melting point, it is 63.7 degrees Celsius.
Arsenic does melt, but has a very high melting point of 1503°F.
Fluorine has a very low melting point of -219.67 degrees Celsius. It is the lightest halogen and exists as a gas at room temperature.
Rust is a compound primarily composed of iron oxide, which has a melting point of around 1,538 degrees Celsius (2,800 degrees Fahrenheit). This melting point is relatively high compared to other common materials. Therefore, it can be said that rust does have a relatively high melting point.
The melting point of NaCl is very different from the melting points of Na or Cl.
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.
Table salt (NaCl) is an ionic solid. Ionic solids are held by electrostatic forces of attraction. These forces are very strong and account for the high melting point of NaCl.
The simple explanation- it takes less energy to beak up the ionic lattice of NaCL than it does to break up the metallic lattice of Mo. Molybdenum is high melting metal, mp. ca. 2600 C. (thats really hot!) The reasons why some metals are high melting and some are low is complex. In simple terms Mo has a very strong metallic bond. Nacl is an ionic compound, these generally have high melting ponts NaCl is ca 800 C (thats also very hot but obviously much less than Mo. Predicting melting ponts is difficult.

No, it is very low. Argon has a melting point of −189.3°C
Wax is an organic molecule made up of nonpolar covalent bonds. So it is not soluble in water and has a reasonable melting point. NaCl is an inorganic salt made of ionic bonds. Because water is polar it can dissolve NaCl. Ionic bonds are very strong though, and so it has a high melting point.
Low, very low.
Salt as its commonly called has a very high boiling point, 2575 degrees F. or 1413 degrees Celsius.
Sodium chloride has a very strong ionic bond between sodium and chlorine. This bond is hard to break apart and force a state change, so it takes a lot of heat to bring it about. This means that the boiling point at which salt becomes a gas is very high.
well it depends if it can melt if the state changes at a hot temperature= high melting point ll ll ll ll ll ll cold ll = low melting point
