Chemistry Question on Classification of elements & periodicity in properties
The correct order of electron affinity of halogens is
A
F>Cl>Br>I
B
I>Br>Cl>F
C
Cl>F>Br>I
D
Cl>F<Br<I
Answer
Cl>F>Br>I
Explanation
Solution
The order of electron affinity of halogens is as Cl>F>Br>I F has lesser value of electron affinity than Cl. It is due to smaller atomic size of F.
