They are in group seventeen. Halogens have seven electrons in their outer energy level. Some examples of halogens are chlorine and astaline.

Halogens are the flourine, chlourine, and the astaline. They are in group 7 or 17 i cant remember. But it has seven electrons in the energy levels.

they are non metals and in group 7A. Halogens are elements such as floruine, chlorine, and iodine.

The halogens are nonmetal elements from group 7. some of the are chlorine, bromine, iodine, and astatine. they are used in making medicines.

Some examples of halogens are floruine, astaline, and chlorine. On the periodic table, they are in group 7A. They also have seven electrons in their outer energy level.

Halogens are some differnet elements that have clorine, florine, astatine, iodine, and bromine in its group. Its group number is 17 and they are all non metals. They are important because they are our outer energy levels.

They are in group 17(7A) and are very reactive. They include elements flourine, chlorine, bromine, iodine, and astatine. They all have 7 valence electrons.

Well this so called Halogens are these things called elements like flourine, chlorine, and staline. They are in the group 17 on the periodic table or something like that. They have 7 electrons in there outer energy level.

Halogens are nonmetalic elements. They are flourine, chlorine, iodine, astaline, and bromine. They react really easily because they are missing an electron on the outer most layer. They are in group 17. Undiscovered element 117, which name is really weird and is ununseptium, may also be a halogen.
