Question

Arrange the non metal iodine,fluorine, bromine, chlorine in decreasing order of their reactivity?​

Answer 1

Answer:

Arrangement of non-metals based on decreasing order of their reactivity is Fluorine>Chlorine>Bromine>Iodine. Explanation: The given elements such as Iodine, Fluorine, bromine, and Iodine are called halogens and they belong to group 17 of the periodic table.

Answer 2

Question

Arrange the non metal iodine,fluorine, bromine, chlorine in decreasing order of their reactivity?​

Answer:

Fluorine>Chlorine>Bromine>Iodine.

REASON

if we move down the group reactivity increases

• When we move down the group the atomic radius increases due to which the ability of the atom of the element to hold incoming electron decreases.

• Due to this, the reactivity ability of these elements decrease down the group.

• Thus fluorine is highly reactive whereas iodine is the least reactive.

• Thus the correct order of elements in decreasing order of their reactivity are as follows:

Fluorine>Chlorine>Bromine>Iodine.
