In general, only the first electron affinity can be measured directly, because negative ions repel electrons. However, the second (and third, if necessary) electron affinity can be estimated using a variation on the Born-Haber cycle. Here are the reactions that must be considered if you need to make oxide ions.

Ionization energies measure the tendency of a neutral atom to resist the loss of electrons. It takes a considerable amount of energy, for example, to remove an electron from a neutral fluorine atom to form a positively charged ion. = 1681.0 kJ/mol. electron affinity of an element is the energy given off when a neutral atom in the gas phase

SOLVED: Which reaction below represents the electron affinity of K? K+(g) + e- → K(g) K(g) + e- → K-(g) K+(g) → K(g) + e- K(g) → K+(g) + e- K(g) + The electron affinity (E ea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion.. X(g) + e − → X − (g) + energy. This differs by sign from the energy change of electron capture ionization. The electron affinity is positive when energy is released on electron capture.

Which Reaction Below Represents The Electron Affinity Of K
The electron affinity (E ea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion.. X(g) + e − → X − (g) + energy. This differs by sign from the energy change of electron capture ionization. The electron affinity is positive when energy is released on electron capture. An atom of Potassium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Potassium. K + e – → K – – ∆H = Affinity = 48.4 kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity.
