(c) F < Cl > Br < I (d) F < Cl < Br > I

Answer 1

Explanation:

option c

I hope it's help u

Answer 2

(a) F > Cl > Br > I

Explanation:

Halogens is the group of elements containing Flourine, Chlorine, Bromine, Iodine, etc. It is called the Group 7 of the periodic table. Halogens are non-metals and the reactivity of halogens decreases as you move down the group. This is the opposite trend to that seen in the alkali metals in Group 1 of the periodic table. Fluorine is the most reactive element of all in Group 7.

Option A is the answer.
