    Electronegativity increases as you go from the bottom left corner of the periodic table to the upper right corner. The element with the lowest electronegativity is thus francium (Fr). However, this element is radioactive, and so generally the least electronegative element that you can really use is cesium (Cs). Generally speaking, this whole first column (the alkali metals) all have very low electronegativities, but the lower down the column, the lower the electronegativity.

    The most electronegative is fluorine (F).

    The lowest known electronegativity belongs to francium (0.7). The lowest electronegativity of a stable element is that of caesium (0.79).
