The halogen in period 3 is chlorine, which is a nonmetal element with the atomic number 17. It is highly reactive and exists as a diatomic gas in its natural form. Chlorine is commonly used in disinfectants, bleaches, and PVC production.
Chlorine is the halogen that is in the same period as potassium. They are both in period 3 of the periodic table.
Chlorine is the halofen present in the third periodg
The halogen in period 2 is fluorine.
The halogen in the 2nd period is fluorine (F).
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.

If you have a periodic table of the elements available, look at the second column from the right. Those elements are often referred to as "halogens". The "rows" in the periodic table are often referred to as the "periods". So the halogen from the third period would be "CL", or chlorine. Glad to help with your homework.
Chlorine is the element located in Period 3 that is used for water purification. It is also a member of the Halogen group.
It is bromine. Edit: NO. It is NOT bromine. The third period halogen is chlorine (Cl). Bromine happens to be in period 4.
Fluorine is in the halogen family and in the second period of the periodic table.
Bromine is a liquid nonmetal halogen in the fourth period of the periodic table. It is the only halogen that exists in a liquid state at room temperature.
Iodine, element number 53 is the halogen (Group 17) element in period 5.
