WebDec 30, 2024 · For example, the electronegativity value of hydrogen is 2.20, and fluorine is 3.98. Their electronegativity difference is 1.78. The value lies between 0.4 and 2.00, implying that the bond type is polar covalent. ... Whereas electron affinity is the amount of energy released once that chemical bond is formed between the atoms. WebElectron affinity is the energy change that results from adding an electron to a gaseous atom. For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol.Because this value is negative (energy is released), we say that the electron affinity of fluorine is favorable.
