Halogens are a series of non-metals in what was formerly known as Group VII and VIIA in the Periodic Table. These are highly chemically reactive elements such as chlorine, fluorine, bromine, iodine, and astadine. They all have 7 electrons in their outer shell which is why they are so chemically reactive.
Fl is the chemical abbreviation of the Halogen Fluorine.
The halogens with their period no. are :- Fluorine (2) Chlorine (3) Bromine (4) Iodine (5) Astatine (6) Tennessine (7) The last two are radio-active and not fully characterised. You will not find them in a school/college lab. NB There are NO halogens in period '1'. The only elements in period '1' are hydrogen(H) and helium(He).
Chlorine is a halogen.
The halogen in the 2nd period is fluorine (F).
