Most Electronegative\u00a0 and Least Electronegative elements in the Periodic table<\/strong><\/span><\/p>\n

In the periodic table down the group<\/strong> atomic size increases<\/strong> and along the period<\/strong> atomic size decreases<\/strong><\/span><\/p>\n

This means Cesium can be considered as the biggest atom and fluorine is the smallest atom of the periodic table (Noble gases, Hydrogen atom and radioactive materials are generally exempted.)<\/em><\/strong><\/span><\/p>\n

This\u00a0means that Cesium has<\/strong> the lowest tendency to attract the shared pair of electrons because of its\u00a0 big size and it is the least electronegative atom<\/strong> in the periodic table. Fluorine<\/strong> is the smallest atom with the highest tendency to attract the shared pair of electron so it is\u00a0 the\u00a0 most electronegative<\/strong> in\u00a0 the periodic table.<\/span><\/p>\n

Scale to Measure Electronegativity<\/strong>.<\/span><\/h2>\n

Electronegativity cannot be measured in Joules or KJ\u00a0 because it is not an energy. Electronegativity is the tendency to pull shared pair of electrons and hence\u00a0 a different scale is used to measure electronegativity, called as\u00a0Pauling Scale.<\/strong><\/span><\/p>\n

All elements lie in the range of 0.8 (value for Cs -least electronegative)\u00a0 to 4.0(value for Fluorine- most electronegative element)<\/span><\/p>\n

Difference\u00a0between Electronegativity and Polarity of the Bond\u00a0<\/b><\/span><\/h2>\n

Difference in electronegativity causes polarity of the bond. With higher\u00a0 difference in electronegativity,\u00a0 there is more polarity in a bond. Three\u00a0 basic categories of chemical bonds-<\/span><\/p>\n
