Concept introduction:
Electron affinity is the ability of an atom by which the neutral gaseous atom adds an electron. It is an exothermic process because energy is released in this process.
Answer to Problem 97A
Amount of energy discharged when electron/s is/are added to an atom in its state of lowest energy is called an electron affinity. On moving down a group, electron affinity values decreases. Electron affinity values increases on moving from left to right on a period in periodic table.
Explanation of Solution
Amount of energy discharged when electron/s is/are added to an atom in its state of lowest energy to produce an anion is called an electron affinity or affinity energy. It is generally represented as EA or E.
On moving down a group, electron affinity values decreases. The values increases on moving from left to right on a period in periodic table.
