Question

Why the lallice energy of
flourides
is greater than chlorides​

Answer 1

Explanation:

I guess you want to ask why ionic fluorides have higher lattice energies than ionic iodides.

On the casual note, lattice energy is the energy stored in a crystal lattice, or the energy needed to bring together ions to form a crystal. Kind of potential energy stored. This depends on coulumbic interaction between charges;(amount of charge and distance between).

So, when charges of ions increase or the distance between them decreases. They are more strongly bonded and thus more energy needed to form that kind of bond hence more lattice energy. Charge as in Mg2+ greater than Na+, distance as in the radius.

Iodine has greater radius and thus more distance making a weaker bond than Fluorine. Less energy needed to bind it resulting in lesser lattice energy than Fluorine. :)

Hope it helps!!!
