How reactive are halogens?

Answer 1

In the Periodic Table, the reactivity of the halogens that are found in Group 17 decreases as you go down the column of elements in this group. The first element of the group is fluorine, and it has the highest reactivity. The other elements in this group are chlorine, bromine, iodine, and astatine.

Answer 2

As we move down the group, the reactivity of hologens decreases. This is so because the size of halogen atoms increases as we move down the group. Thus the attraction between nucleus and electrons of the outermost shell decreases which enhances its capability to form cations by loosing electrons and hence inhibits its capability to react with metals in order to complete its octet.

Answer 3

Halogens like fluorine, chlorine, bromine, iodine, and astatine are highly reactive elements due to their strong tendency to gain an electron to achieve a full outer electron shell. They readily form salts with metals and can react vigorously with other elements and compounds. Their reactivity decreases as you move down the group on the periodic table.

Answer 4

The reactivity of halogens decreases with increasing atomic number.

Answer 5

The smaller halogens are very reactive, fluorine and chlorine but the larger halogens are stable bromine and iodine. Both bromine and iodine are used as topical antiseptics on wounds.

Answer 6

Metals Period - reactivity decreases as you go from left to right across a period
