Correct option is C)

Option (C) is correct. Additional electrons are repelled less effectively by -electrons in -atom than by -electrons in -atom.Fluorine's electron affinity is smaller than chlorine's because of the higher electron - electron repulsions in the smaller orbital compared to the larger orbital of chlorine.

The properties like ionization potential, electronegativity, electron affinity and power of the catenation of the member in a group depend on many factors. For example, the smaller the size of the atom greater will be the ionization potential. At the same time symmetry in the electronic configuration of the elements also play a part in their ionization energy. Smaller the atomic size, greater will be the mutual electronic repulsion and lesser will be electron affinity. Similarly, the catenation which is a direct result of M - M bond strength is also affected by similar considerations.

The correct decreasing order of catenation among group elements is _________.
