Question

Which pair of elements has reactivity that is similar to chlorine, Cl? F. Fluorine and Argon G. Fluorine and Iodine H. Sulfur and Bromine J. Sulfur and Argon

Answer 1

halogens

Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

Answer 2

The pair of elements that have reactivity similar to chlorine are fluorine (F) and iodine (I).

HALOGEN:

• Halogens are a group of elements in group 7 of the periodic table. They are characterized by the possession of one valence electron in their outermost shell.

• Halogens are very reactive elements and form salts with most metals. Halogens include Chlorine, fluorine, iodine etc.

• Since member elements in the same group behave similarly in terms of reactivity, fluorine and iodine will exhibit the same reactivity as chlorine.
