Addition of electron to (Cl) will have negative electron affinity.
Addition of electron to (Cl*) will have negative electron affinity.
Addition of electron to (O) will have negative electron affinity.
Electron affinity is the energy change associated with adding an electron to a neutral atom to form a negative ion. Oxygen (O) typically has a positive electron affinity because it releases energy when an electron is added to form an O- ion.
