Explanation:Lattice energy is the energy required to break an ionic compound (solid) into gaseous ions.
Lattice energy increases as the size of the ions decreases.MgO has the highest lattice energy while HCl has the lowest magnitude of lattice energy k^+ and Cl^- ions have the largest size.
The lattice energy is one that depend on the attraction between oppositely charged ions in a compound/substance.
Following up with this the greatest forces of attraction will exist between ions that have the smallest radii.
And, because the attraction depends on the product of the charges, we prioritize ions with the greatest charge.
The smallest pair of ions will be able to get closest to each other relative to others. This implied that the smallest distance between centres will have the largest lattice energies relative to others.
I don't know what the exact word is, but I do know that the bigger an objects mass is the more it will attract other objects toward it, mainly smaller objects with less mass. it might be gravity or something around those lines....is it a multiple choice question?
