Lattice Energy
« on: January 20, 2009, 07:39:10 PM »
Which would have lesser lattice energy and why?
Na\2O and MgCl\2.

Does it have to do with ion sizes?

What does lattice energy depends on?

ion size and charge play a big role. you are actually considering the charge density.

lattice energy depends on both the atomic radii and the charge of the irons.

LE = K (q1 q2) / r2
as the charge increases the L.E increases..
as the radii increases L.E decreases..

since charge is the same here ..i guess it depends on radii
