same, with Li", for instance, exchanging more slowly than Cs*.
a.
B. Be?* exchanges more slowly than Al3+.
U C. Cr3* has an unusually low rate of exchange.
d.
The exchange rate for Cr2+ is only slightly higher than that of Cr3t.
O e. All of the trivalent metal cations (M3+) have approximately the same rate
of exchange due to their similar charge densities.
f.
Metal ions of the second and third transition series exhibit high rates of
exchange due to their larger ionic radii compared with the metal ions of
the first transition series.
