WebElectronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated … hel ved as

Electron Affinity: Definition & Chart StudySmarter

WebElectron affinity refers to the ability of elements to release energy, thus showing the ease and spontaneity, of adding an extra electron to the sole atom. Another difference is that electronegativity is a value from 0 to 4.0, while electron affinity is a defined thermodynamic constant for each element in kJ per mole. WebExpert Answer. 17.
