प्रश्न
Arrange the following in increasing order of property indicated
F, Cl, Br, I (electron affinity)
Advertisements
उत्तर
I < Br < F < Cl
Electron affinity decreases down the group due to increase in atomic size as it results in more distance between nucleus and last shell to which incoming electron enters. Hence, incoming electron feels less attraction from the nucleus.
