Electronegativity can be found or predicted using its periodic trend.

Electronegativity is the measure of the ability of an atom that is bonded to another atom to attract electrons to itself. Elements that attract electrons the most are found in the upper right corner of the table.

Electronegativity increases across a period and decreases down a family.

Fluorine is the most electronegative element with a value of 4. The least electronegative elements are Cesium and Francium in the opposite corner. The noble gases have zero electronegativity because their electron shells/energy levels are full.
