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?
No matters what results are waiting for us, it's nothing but the DESTINY!!!!!!!!!!!!

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
