The lithium ion, \(\ce{Li+}\), is smaller than the sodium ion. How does the melting point of lithium oxide, \(\ce{Li2O}\), compare to that of sodium oxide?
A.
It is higher because smaller ions have a higher lattice energy.
B.
It is the same because the charges are the same.
C.
It is lower because smaller ions have a smaller lattice energy.
D.
It is impossible to predict because there is insufficient information in the problem
