'As the atomic radius increases down Group 7 halogens,the ability to accept an electron decreases,(this, I understand).
As a result,the reactivity of halogens decreases down the group and also the oxidising power/ability of the halogens decreases down the group"
It is the part in bold that I can't understand.Does the oxidising power stated here refer to the elements' ability to act as oxidising agents?Atleast this is what I think, considering the Cl2 water test,but elsewhere ,my notes on the periodic trends state that across a period 'the reducing power/reducing ability infact,increases across a period'.
Now I'm confused,'cos if the first were true,that would mean the ability to undergo oxidation would increase across a period which seems a bit absurd,I think?
My other problem is, "down the electrochemical series the higher metals replace the lower ones,but for the non-metals in the series the reverse is true,the nonmetal lower down displaces the one higher",but how so,I tried googling but I didn't get a comprehensive answer.
Hope my problem is clear and I really hope someone can help me understand .
THANX IN ADVANCE
