How do you find the electronegativity of an element?

For exact values you must consult a table, such as one found in a chemistry book.

Flourine (upper right on the periodic table) has the highest electronegativity value of 4.0.

Francium (lower left on the periodic table) has the lowest value of 0.7.

As far as general trends go, the closer to fluorine you are the more electronegative the element, and the closer to francium you are the less electronegative the element.
