Question

F, CL, Br, I arrange these elements in increasing order of their electron affinities

Answer 1

Hello friend!!!

Here's your answer

I< Br< F< Cl

Cl has the most electron affinity in the periodic table due to its small size than Br and I & more z-effective than F.

HOPE THIS HELPS..... ☺️

Answer 2

Elements in Increasing order of their electron affinities are I<Br<F<Cl.

Electron affinity:

• The amount of energy released when an electron is coupled to a neutral atom or molecule in the gaseous state to create an anion is known as the electron affinity of an atom or molecule.
• In light of Linus Carl Pauling's discovery of electron negativity, the idea of electron affinity was uncovered in 1901.
• When an electron in a gaseous state is given to a neutral atom, the amount of energy that changes is known as the electron affinity.
• Electron Affinity is often exothermic because energy is produced when an electron is added to a neutral atom.
• The second electron affinity may be positive as a result of electrical repulsions.

Why electron affinity of Chlorine is more than Fluorine?

• Because chlorine has a greater size to accommodate electrons while fluorine is too small to accommodate electrons when size drops from left to right inside a period, chlorine has a higher electron affinity than fluorine.
