WebJul 1, 2024 · It is important to notice that the elements most important to organic chemistry, carbon, nitrogen, and oxygen have some of the highest electronegativites in the periodic table (EN = 2.5, 3.0, 3.5 respectively). Metals, on the left, tend to be less electronegative elements, with cesium having the lowest (EN = 0.7). WebElectronegativity. Electronegativity is a measure of an atom’s attraction for the electrons in a bond. Across a period from left to right the electronegativity of atoms increases. WebElectronegativity increases from bottom to top in groups, and increases from left to right across periods .
