Assessment: WAEC SSCE - Chemistry - 2016 (Objective) Subject: Chemistry

Question 1 Report

The energy which accompanies the addition of an electron to an isolated gaseous atom is
Answer Details
The energy which accompanies the addition of an electron to an isolated gaseous atom is called electron affinity. When an atom gains an electron, it becomes a negatively charged ion. The energy released or absorbed when this process occurs is the electron affinity. If energy is released when an electron is added to the atom, then the electron affinity is negative, and if energy is absorbed, then the electron affinity is positive. Therefore, the correct option is "electron affinity."
