Question

If the charge on an ion is greater,
the lattice energy is.​

Answer 1

Answer:

Because the ionic radii of the cations decrease in the order K+ > Na+ > Li+ for a given halide ion, the lattice energy decreases smoothly from Li+ to K+. Conversely, for a given alkali metal ion, the fluoride salt always has the highest lattice energy and the iodide salt the lowest.

Explanation:

As the radius of ions increases, the lattice energy decrease. ... This is because with the increase of size of ions, the distance between their nuclei increases. Thus the attraction between them decreases and finally the less lattice energy released during the process.

Answer 2

Answer:

As the charge of the ions increases, the lattice energy increases. as the size of the ions increases, the lattice energy decreases.
