Select all correct statements dealing with electron affinity. O It is the enthalpy change associated with the removal of an electron from a gaseous atom or ion. O It is the enthalpy change associated with the addition of an electron to a gaseous atom or ion. O In general the first electron affinity is: X(g)X*(g) + e O In general the first electron affinity is: X(g) + eX(g) Why are electron affinities usually exothermic? O the incoming electron experiences a repulsion from the nucleus, lowering the potential energy of the electron. O the incoming electron experiences an attraction to the nucleus, lowering the potential energy of the electron O the incoming electron experiences a repulsion from the nucleus, increasing the potential energy of the electron. O the incoming electron experiences an attraction to the nucleus, increasing the potential energy of the electron
