question 64

Multiple Choice

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.
