Iodine, element number 53 is the halogen (Group 17) element in period 5.
Fluorine is the halogen in period 2 which is a gas.
Iodine (I) will do it
Fluorine, the ninth element.
This chemical element is astatine (At).
It is astatine.
Chlorine

Fluorine, F

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
Bromine is in 4th period of periodic table.
Nitrogen: nitrogen is a pnictide, group 15 and period 2 in the periodic table of MendeleevBromine: bromine is a halogen, group 17 and period 4 in the periodic table of Mendeleev
fluorine
Astatine is the 6th period halogen.
Chlorine is the halofen present in the third periodg
Chlorine is the element located in Period 3 that is used for water purification. It is also a member of the Halogen group.
chlorine
Iodine
C is located in the second period and Ba is located in the sixth one.
bromine
Fluorine
It is bromine. Edit: NO. It is NOT bromine. The third period halogen is chlorine (Cl). Bromine happens to be in period 4.
