Answer :
Answer;
D) High melting point and strong intermolecular forces.
Explanation;
- Sodium which is a metal reacts with chlorine which is a non metal to form sodium chloride which is the result of ionic bond.
- Solid sodium chloride forms a giant ionic structure which contains each sodium atom joined to six chloride ions, and each chloride ion surrounded by six sodium ions. This arrangement forms a crystal lattice which is a crystal structure made up of strong ionic bonds between chlorine and sodium atoms.
- The crystal structure of sodium chloride has a very high melting point because of strong ionic or intermolecular forces between sodium ions and chloride ions.
