Question

why does sodium chloride has a high melting point​

Answer 1

Answer:

It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. ... Sodium chloride is made from Na + ions and Cl - ions and has a melting point of 801°C.

please thanks thanks

Answer 2

Explanation:

Sodium chloride has a high melting point and boiling point because of the strong electrostatic attraction between its positive and negative ions. This requires more heat energy to overcome the force of attraction
