Question

10. Lattice energy depends on
1) only radius of cation
2) only radius of anion
3) cation to anion radius ratio
4) sum of the radii of cation​

Answer 1

Answer:

4

Explanation:

sum of the radii of cation

as lattice energy is inversely proportional to the sum of radii of cation and anion

when there is change in radii of cation then there is change in sum then lattice energy decreases and vice versa.

Answer 2

Answer:

sum of the radii of cation and anion
