Electronegativity is not a uniquely defined property and may depend on the definition. This page explores the trends in some atomic and physical properties of the Group 2 elements: beryllium, magnesium, calcium, strontium and barium. Therefore, metals are electropositive and non-metals are electronegative in nature. So, barium < strontium < calcium < magnesium If we ignore the inert gases and elements for which no stable isotopes are known, we see that fluorine ($$\chi = 3.98$$) is the most electronegative element and cesium is the least electronegative nonradioactive element ($$\chi = 0.79$$).

Highest to Lowest: 1. spontaneous combustion - how does it work? P is the second highest. The higher the electronegativity is the more it attracts the electrons towards it. The most electronegative elements are O, F and N. For the representative elements, electronegativity increases as you go across a period and decreases as you go down a group. Fluorine 4.0 EN. Please note that the elements do not show their natural relation towards each other as in the Periodic system. electronegativity in increasing order is given below: Sr $<$ Ge \$
