Respuesta :

Sodium chloride has a high meltint point because of the strong electrostatic attraction between its positive and negative ions.

Common table salt (NaCl) have a high melting point because of Ionic Bonds.

Ionic Bonds:

It is the bond in which a metal donate its electron to a nonmetal element. For example - NaCl.

  • Na is a metal and has 1 electron in its outer shell.
  • Cl is non-metal and has 7 electrons in its outer shell.

When sodium donates its valence electron to chlorine, Na become a positive ion and Cl become a negative ion. Hence opposite ions attract each other and form a strong bond.
