Types of bondings

  1. May 15, 2008 #1
    Is there any rule that I can use to determine if an atom will consist of ionic bondings, covalent bondings or polar covalent bondings? I'm thinking of difference in electronegativity on the Pauling scale.

    you mean a compound?!

    the electronegativity difference should be more than 1.7 for the compound to be ionic.

    also, when there is an ion of high charge density(e.g. in AlCl3), covalency may occur.
