Question

Quizplus · Accepted Answer

The energy released on adding an electron to an isolated gas phase atom is known as electron affinity. It is a measure of how strongly an atom attracts an additional electron. The higher the electron affinity, the greater the energy released upon addition of an electron, indicating a stronger attraction for electrons.
