Because they are all have the same amount of outer electron or covalent electron or charge.
Fluorine, Chlorine, Bromine, Iodine, and Astatine.
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.
Halogens are a series of elements from group 17.Fluorine (F)Chlorine (CI)Bromine (Br)Iodine (I)Astatine (At)Ununseptium (Uus)
+1 ions are formed when an element in the first period loses an electron, they have 1 valence electron. These are hydrogen, lithium, sodium, potassium etc
Group 17 elements are called halogens. They include Fluorine-F, Chlorine-Cl, Bromine-Br, Iodine-I, and Astatine-At. They are all nonmetals and are reactive because they have 7 electrons in their outer shell, just one electron short of having a full shell.
Fluorine, Chlorine, Bromine, Iodine, and Astatine.

halogens (fluorine, chlorine, bromine, iodine and astatine)
The elements in Group 17, which are fluorine, chlorine, bromine, iodine, and astatine are known as the halogens.
bromine <><><><><> Halogens are group 17 elements, like fluorine, chlorine, bromine, iodine, astatine, and uus-117.
Halogens F (fluorine), Cl (chlorine), Br (bromine), I (iodine), At (astatine)
Halogens: fluorine, chlorine, bromine, iodine, astatine, Uus.
Bromine is in Group 7: The Halogens, below Fluorine and Chlorine but above Iodine and Astatine.
The family name is halogens and the members are fluorine, chlorine, bromine, iodine and astatine.
The halogens are: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).They are the 2nd column from the right in the Periodic Table.fluorineChlorine, bromine, fluorine, iodine
Fluorine (and also chlorine, bromine, iodine) are all members of the halogens group; they are nonmetals, group 17, period 6 in the periodic table of Mendeleev.
Yes, Halogens are the name of a group of non-metal elements found on the Periodic Table, Group 7A (or 17). Halogens include fluorine, chlorine, bromine, iodine and astatine.
