    If the difference in electronegativities between the two atoms is 2.0, or greater, the bond is ionic.

    Here the electronegativity is 2.34 so it's an ionic bond.

    But then they have given us the electronegativity table and has asked us to determine the bond type using that right? So I thought she knew about the electronegativity.

    it is the tendency of an atom to attract a bonding pair of electrons

    they have given us the electronegativity of K and Cl Find the difference if it is greater than 2 they are considered as ionic bonds

    the difference was 2.34 so it is ionic? @Rushwr

    Nonpolar covalent has an electronegtivity difference of 0.2 - 0.5. A polar covalent has an electronegtivity difference less than 1.6. Ionics have an electronegativity greater than 2.0. Yes, 2.34 is greater than 2, so it is ionic.

    Electrongetivity increases to the right, and upwards of the periodic table

    Electronegativity is the ability of an element to pull electron density towards itself, so it causes polarity. Polarity is a difference in the electron density from one end of a molcule/bond to the other. So if you bond something with a high electronegativity to something with a low electronegativity, this big difference causes a partial positive charge on one atom, and a partial negative charge on the other, which is polarity. But similar electronegativities give bonds with little or no polarity.

    what she is trying to say is that when a highly electronegative element bonds with a less electronegative element part of it becomes -ve and part +ve, this is polarity. What we need to do now is to find out which one of d options has the highest polarity value

    ok so all u need to do is to take d value of d highly electronegative element and subtract the less electronegative element from it. An example is this:

    ok so because F is more electronegative, and hydrogen less electronegative the bond becomes partly -ve and partly +ve. The highly electronegative one has the -ve charge while the less electronegative one has the positive charge

    -ve means negative and +ve means positive

    Fluorine is more electronegative and so it should have the -ve charge
