Which аtоm hаs the lаrgest electrоnegativity, accоrding to this graph? Image Description Graph of electronegativity (y-axis) versus atomic number (x-axis). Hydrogen, atomic number 1, is shown with an electronegativity of around 2.1. Lithium, atomic number 3, to Fluorine, atomic number 9, is shown starting at an electronegativity of 1 with Lithium and going up diagonally to Fluorine with an electronegativity of 4. Sodium, atomic number 11, to Chlorine, atomic number 17, is shown starting at an electronegativity of 0.9 with Sodium and going up diagonally to Chlorine with an electronegativity of 3.1. Potassium, atomic number 19, to Bromine, atomic number 35, is shown starting at an electronegativity of 0.8 with Potassium and curving up to an electronegativity of 1.9 where the atomic number is 27 to 29, before going diagonally up to Bromine with an electronegativity of 3.
