Which would you expect to have a higher melting point: sodium chloride,NaCl,or cesium chloride,CsCl? Why?
A)The cesium chloride has a higher melting point because larger ions of the same charge are able to attract more ions of the opposite charge.
B)The cesium chloride has a higher melting point because its ions are smaller,which makes the charges more dense.
C)The sodium chloride has a higher melting point because of the greater charges of the ions,and hence the greater force of attractions between them.
D)The sodium chloride has a higher melting point because its ions are smaller,which allows oppositely charged ions to get closer.

Question

Quizplus · Accepted Answer

Sodium chloride (NaCl) has a higher melting point than cesium chloride (CsCl) because its ions are smaller. This allows the oppositely charged ions to get closer, resulting in stronger electrostatic attractions that require more energy (in the form of heat) to overcome.
