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.
Astatine is the 6th period halogen.
It is bromine. Edit: NO. It is NOT bromine. The third period halogen is chlorine (Cl). Bromine happens to be in period 4.

This chemical element is astatine (At).
Bromine. :)
Chlorine, the halogen in period 3.
Nitrogen is not a halogen; nitrogen is a pnictide, group 15 and period 2 in the periodic table of Mendeleev.
