Ionic Bond Strength: LiF vs K20

Click For Summary
SUMMARY

The discussion centers on the factors influencing ionic bond strength, specifically comparing lithium fluoride (LiF) and potassium oxide (K2O). It is established that LiF exhibits a stronger bond strength due to its higher lattice energy, despite K2O having a greater ionic character. The order of increasing ionic character among the compounds is identified as N2 < SO2 < ClF3 < LiF < K2O. Key concepts such as Coulomb forces, lattice energy, and polarizing power are crucial to understanding these differences.

What are the factors that determine the strength of an Ionic bond?
Taking the example of LiF and K20, why does LiF have a stronger bond strength?
 
Chemistry news on Phys.org
Think about coulomb forces.
 
Yeah... not really working for me.
I need the answer.

The question I had was :

Please arrange the bonds in order of the increasing ionic character of the molecules (without looking at the electronegativity table) -
LiF, K2O, SO2, N2 and ClF3

Of which the answer was -
N2<SO2<ClF3<LiF<K2O

I can't understand as to why K2O has a stronger ionic character than LiF.
 
So what is the question? In the subject you mentioned ionic bond strength, now you ask about stronger ionic character. These are two different things.
 
Nevermind, understood the problem I was having.
Thanks anyway.
 
Also you can think in terms of lattice energy and polarising power or polarisability. :)
 
Will do. Thanks :)
