The relative sizes and the ionic radii (in picometers) of
several ions are shown in the figure above. Using
Coulomb's law and the information in the figure as a
basis for a prediction, which of the following lists the
salts made from these ions in order of decreasing
melting point?
O A.
O
O c.
KF > RbCI > NaBr
B. RbCl > KF > NaBr
D.
NaBr > RbCI > KF
KF > NaBr > RbCl
