Which element has the highest electron affinity? - Quora

WebElectron affinity is the measure of the energy released when an electron is added to an atom to create a negative ion. This property is measured when the elements are in a gaseous state only - this is because it is measured with the atoms sufficiently separated so as to not have their energy levels be affected by surrounding atoms. WebThe electron affinity of an element is a measurable physical quantity, namely, the energy released or absorbed when an isolated gas-phase atom acquires an electron, measured in kJ/mol. Electronegativity, on the …

WebElectronegativity is the measure of the energy required to remove an electron from an atom. Electronegativity is the measure of the repulsive force between two electrons in the same orbital. Electronegativity tends to decrease …

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 …
