Which of the following is true regarding the attractive force that holds sodium chloride in the solid state?
I.It is electrostatic.
II.It is termed ionic bonding.
III.It depends on the distance between the sodium and chloride.
IV.It operates only between adjacent sodium and chloride.

Question

Which of the following is true regarding the attractive force that holds sodium chloride in the solid state? 
I.It is electrostatic.
II.It is termed ionic bonding.
III.It depends on the distance between the sodium and chloride.
IV.It operates only between adjacent sodium and chloride.

Quizplus · Accepted Answer

I is true because the attractive force is an electrostatic force between positively charged sodium ions and negatively charged chloride ions. 
II is true because the bonding is between two ions of opposite charges, a cation (sodium) and an anion (chloride). 
III is true because the attractive force depends on the distance between the ions; it decreases as the distance between them increases. 
IV is false because the attractive force operates between all sodium and chloride ions in the crystal lattice, not just adjacent ions.
