I just want to be completely sure of these answers before submitting them, since I just get one opportunity to do so. If someone could check this, it would be deeply appreciated. Also, if something is wrong, please explain... Thanks
#1 is a little confusing with the use of the word largest. I think it is common practice to list LiF as the largest lattice energy but technically it is the smallest number.
Lattice energies are as follows:
LiF = -1036 kJ/mol
NaF = -923 kJ/mol
LiCl = -853 kJ/mol
NaCl = -787 kJ/mol
Therefore, I think you answer to #1 is ok but do keep the negative in mind.
2, 3, and 4 look ok to me.
