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.

Iodine, element number 53 is the halogen (Group 17) element in period 5.

Bromine is in 4th period of periodic table.
Fluorine
Astatine is the 6th period halogen.
Chlorine, the halogen in period 3.
chlorine
Chlorine is the element located in Period 3 that is used for water purification. It is also a member of the Halogen group.
The halogen that is in period 3 of the periodic table is chlorine (Cl). Chlorine is a member of Group 17 (Group VIIA), also known as the halogens. Other members of this group include fluorine (F), bromine (Br), iodine (I), and astatine (At). Chlorine is a highly reactive nonmetal and is commonly found in compounds such as sodium chloride (table salt).

Chlorine is the halofen present in the third periodg
bromine
It is bromine. Edit: NO. It is NOT bromine. The third period halogen is chlorine (Cl). Bromine happens to be in period 4.
Iodine, element number 53 is the halogen (Group 17) element in period 5.
