This chemical element is astatine (At).
The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
The halogen in the 2nd period is fluorine (F).
The short form electron configuration of halogens in period 6 is [Xe] 4f^14 5d^10 6s^2 6p^5. This indicates that a halogen in period 6 has a noble gas core of xenon followed by valence electrons in the 6s and 6p orbitals.
Chlorine is the halogen that is in the same period as potassium. They are both in period 3 of the periodic table.
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.
Iodine, element number 53 is the halogen (Group 17) element in period 5.
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.
The element symbol for the halogen in the fifth period is Iodine, with the chemical symbol I.
Chlorine is the element in the halogen family located in period 3 of the periodic table.
The halogens with their period no. are :- Fluorine (2) Chlorine (3) Bromine (4) Iodine (5) Astatine (6) Tennessine (7) The last two are radio-active and not fully characterised. You will not find them in a school/college lab. NB There are NO halogens in period '1'. The only elements in period '1' are hydrogen(H) and helium(He).
Yes, chlorine is in the second period of the periodic table and belongs to the halogen family, along with fluorine, bromine, iodine, and astatine.
