Question

Lattice energy of a solid increases if :
(a) size of ions are small
(b) charges of ions are small
(c) ions are neutral
(d) none of the above

Answer 1

Answer:

the answer will be a) size of the atoms are small

Explanation:

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

Answer 2

Answer:

Heyaa✌️✌️

Your right option is a)

Lattice energy is defined as the energy required to separate a mole of an ionic solid into gaseous ions.

Lattice energy is defined as the energy required to separate a mole of an ionic solid into gaseous ions.The 2 factors that contributes to the lattice energy of an ionic solid are charge on the ions & the size of the ions.
