Halogens are highly reactive. This high reactivity is due to the high electronegativity of the atoms due to their high effective nuclear charge. They can gain an electron by reacting with atoms of other elements.
Halogen is the family of salt producing elements.
Yes, it is. Though rarely talked about Astatine is in the Halogen family.
The halogen family
Fluorine, chlorine, bromine, iodine, and astatine. All of the elements in the halogen family are nonmetals.
Only Fluorine belongs in the halogen family.
Halogen
Iodine belongs to group 17. It is in the family called the halogens.
Well the halogen family is very reactive and the noble gasses are not reactive at all.
The halogen family of elements (fluorine, chlorine, bromine, iodine, and astatine) are found pretty much everywhere on Earth.
Astatine is similar to the halogen family
