The electronegativity of an element is a measure of its ability to attract electrons in a chemical bond. The Pauling scale is commonly used to quantify electronegativity values. On the Pauling scale, the electronegativity of nitrogen N is 3.04, and the electronegativity of oxygen O is 3.44.To find the electronegativity difference between nitrogen and oxygen in a molecule of nitrous oxide N2O , subtract the electronegativity of nitrogen from that of oxygen:Electronegativity difference = Electronegativity of O - Electronegativity of NElectronegativity difference = 3.44 - 3.04Electronegativity difference = 0.40So, the electronegativity difference between a nitrogen atom and an oxygen atom in a molecule of nitrous oxide N2O is 0.40.
