List of halogen

Answer 1

HalogensA halogen is one of the highly reactive elements located in group 17 of the Periodic Table. The halogens (in increasing Atomic Mass) are: fluorine, chlorine, bromine, iodine, and astatine.

Each of these nonmetallic elements is related by the fact that each one has an outermost electron shell (valence shell) that is one electron short of being full. That drives these elements to react with any other atoms from which they can borrow that single electron, including themselves. The halogens are all diatomic, meaning they naturally pair up to form two-atom molecules such as F2, Cl2, Br2, etc. (Note: astatine is very rare and should theoretically be diatomic, but it's inconclusive).

Answer 2

a halogen is any element on the periodic table of elements that falls into group (or family) 17. a halogen has 7 valence electrons. some examples of halogens are fluorine and chlorine.

Answer 3

Group VII (group seven) of the periodic table. They are all halogens.

These are:

F - fluorine

Cl - chlorine

Br - bromine

I - iodine

At - astatine
