Q. Which one of the following statement is false?
A) The electron affinity of chlorine is less than that of fluorine.
B) The electronegativity of fluorine is more than that of chlorine.
C) The electron affinity of bromine is less than that of chlorine.
D) The electronegativity of chlorine is more than that of bromine.
Explanation
(a)
The electron affinity of fluorine is lower than that of chlorine due to the very small size of fluorine in which negative charge is highly concentrated and repels the incoming electron thereby reducing the force of attraction of nucleus towards the adding electron and hence, decreasing the electron affinity.
Thus, chlorine has highest value of electron affinity.
