A) size of ions is small
B) charges of ions are small
C) ions are neutral
D) none of the above
Correct Answer: A
Solution :
Key Idea: According to Born-Lande equation \[U=\frac{{{z}^{+}}{{z}^{-}}{{e}^{2}}AN}{{{r}_{node}}}\left( \frac{1}{n}-1 \right)\] where U is lattice energy \[{{r}_{node}}\]is interionic distance \[\because \] \[U\propto \frac{1}{interionic\text{ }distance}\] \[\therefore \]Ions should be of small size to have high lattice energy.You need to login to perform this action.
