Question

The electron affinity values for the halogens show the following trend:

• A. $F<Cl>Br>I$
• B. $F<Cl<Br<I$
• C. $F>Cl>Br>I$
• D. $F<Cl>Br<I$
• E. $F>Cl<br/>I$

Answer 1

Answer: (A)

Electron affinity decreases with increase in atomic size. So, the correct order of electron affinity of halogens is $F<Cl>Br>I$
