Astatine(At) is the 6th period halogen element.
It is a solid and black in colour.
It is radio-active.
It has not been fully characterised.
You will NOT have it in a school/college lab.
The other halogens with their period no. are:-
Fluorine (2)
Chlorine (3)
Bromine (4)
Iodine (5)
Tennessine/Ts (7) : Radio active and not fully characterised.
What else can I help you with?
What is the name of the halogen in the 2nd period?

Is chlorine in the second period of the halogen family?
Yes, chlorine is in the second period of the periodic table and belongs to the halogen family, along with fluorine, bromine, iodine, and astatine.
What halogen is in period 6?
This chemical element is astatine (At).
A covalent compound formed between an element in period 2 and a halogen?
An example of a covalent compound formed between an element in period 2 and a halogen is hydrogen fluoride (HF). This compound is formed by the sharing of electrons between the hydrogen atom (period 1) and the fluorine atom (halogen).
