Electron affinity is the energy change that occurs when an electron is added to a gaseous atom. For most atoms, would you expect the sign for this energy change to be positive (energy required) or negative (energy released) and why? O Negative, because energy is required to add an electron. O Negative, because energy is released to add an electron. O Positive, because energy is released to add an electron. O Positive, because energy is required to add an electron.
