The lattice energy of KF. KCI, KBr and KI follow
the order
a)KF > KCl> Kr>KI
(b) KI > KBr > KCl>KF
(c) KF > KCl > KI > KBr
(d) KI> KBr > KF > KCl. how????​

Answer 1

Answer:

D

Explanation:

they are the noble Gases

and other way says that is also 18 group elements

Answer 2

The lattice energy of KF, KCI, KBr and KI follow  the order:

           KF > KCl > Kr > KI

Explanation:

Lattice energy is defined as the energy released when formation of 1 mole of an ionic compound occurs due to the combination of its constituent ions.

Also, lattice energy is inversely proportional to the distance between the cation and anion. And, when we move down a group then there occurs an increase in the atomic radii of the atoms.

This means that smaller is the ionic distance between the cation and anion, more will be the lattice energy between the atoms.
