Ionic bond strength

  1. Oct 3, 2011 #1
    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?

    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 :)
