Explanation:
Halogens:
Halogens belong to p-block elements.
The halogen elements are the elements in Group 17 of the periodic table.
Group 17 occupies the second column from the right in the periodic table.
It contains the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At).
The term “halogen” means “salt-former” because these elements will readily react with alkali metal and alkaline earth metals to form halide salts.
Halogens and their states of matter:
Fluorine and chlorine: Gases
Bromine: liquid
Iodine: solid
Astatine : solid
