Question

The decreasing oxidising ability of the halogens in aqueous solution down the group is evident from their standard electrode potentials.

what is the meaning of this line ?​

Answer 1

Answer:

Both bond energies and electron affinities decrease down the group as the nuclear pull on the outer electrons decrease. The change in electron affinities is most significant and so oxidizing ability decreases down the group as the nuclear pull on the outer electrons decreases down the group
