17. Which statement best describes the trend in boiling points of the group 1 metals? (A) Going down group 1, the ionic charge increases, so the attractive forces between the ions
and the delocalized electrons becomes stronger; hence the melting point increases.
(B) Going down group 1, the ionic radius decreases, so the attractive forces between the ions
and the delocalized electrons becomes stronger; hence the melting point increases.
(C) Going down group 1, the mass of the ions increases, so the attractive forces between the ions
and the delocalized electrons becomes weaker; hence the melting point decreases.
(D) Going down group 1, the ionic radius increases, so the attractive forces between the ions and
the delocalized electrons becomes weaker; hence the melting point decreases.
