Question

Quizplus · Accepted Answer

Electron affinity is defined as the energy change that occurs when an electron is added to a neutral atom to form a negatively charged ion. This energy can be either positive or negative, depending on the atom. If the energy change is positive, then electron affinity is a positive quantity. If the energy change is negative, then electron affinity is a negative quantity. Therefore, electron affinity is not always a positive quantity.
