Question

write short note on halogen or group 17 element​

Answer 1

I hope this helps you

The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Although astatine is radioactive and only has short-lived isotopes, it behaves similar to iodine and is often included in the halogen group. Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. This characteristic makes them more reactive than other non-metal groups.

Answer 2

Answer:

The halogens are the elements that form group 17 of the periodic table. They are reactive nonmetals and include fluorine, chlorine, bromine, and iodine.

Halogens are highly reactive non-metals. These elements greatly resemble in property with each other. Group 17 elements are collectively called as halogens (In Greek: halo means salt and genes mean producing, so collectively salt producing) and it consists of fluorine, chlorine, bromine, iodine, and astatine.
