Question

lithium iodide lattice energy is low why?
​

Answer 1

Explanation:

Based on my knowledge, lattice energy is proportional to the multiplcation of the charge of the ions, divided by the sum of the radius of ions, as follows. Since iodide has a larger radius than fluoride, by this equation lithium iodide would have a less exothermic lattice energy (lower lattice energ

Answer 2

Lithium is in group 1, it is the property of group 1 metals that down the group the reactivity increases for this reason the lithium iodide lattice energy is low .
