    Electronegativity trends.....

    In the same period, electronegativity increases from left to right.

    In the same family (column) electronegativity decreases going down.

    Of course we all know that F is the most electronegative element, followed by O and then N. C is in period 2, next to N, but I is a halogen and the halogens have high electronegativities.  So for C and I its a toss-up. Ba is the least electronegative of the bunch.

    F

    The elements get more electronegative as they go up and to the right (excluding noble gases)

  • Look at an electronegativity periodic table. I think the trend was the higher and more to the right on the table, the less electronegative, but it's been more than a year and I'm probably wrong
