Question

Arrange the non metals : iodine fluorine bromine chlorine in decreasing order of their reactivity

Answer 1

Heya,

The arrangement in decreasing order is as follows:-

1 fluorine
2 chlorine
3 bromine
4 iodine

HOPE IT HELPS:-))

Answer 2

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.
• They are also called as non-metals and there exact order in the group is as follows

   Fluorine

   Chlorine

   Bromine

   Iodine

   Astatine

• 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 Astatine is the least reactive.
• Thus the correct order of elements in decreasing order of their reactivity are as follows:

Fluorine>Chlorine>Bromine>Iodine.
