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.
