Question

In solid NaCl, each sodium ion is surrounded by six chlorine ions and each chlorine ion is surrounded by six sodium ions. This arrangement results in a A) malleable noncrystalline structure. B) ductile, malleable solid with mobile electrons. C) weak crystalline solid that conducts electricity. D) high melting point and strong intermolecular forces.

Answer 1

Answer: D

Explanation: The answer is D.

Answer 2

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.
