Cl
- C
I
- D
At
Astatine is extremely rare and is considered one of the rarest naturally occurring elements on Earth. It is radioactive element with very short half-lives and thus does not occur naturally.
a) F (Fluorine): Fluorine is not a rare halogen. It is the first element in the halogen group and is relatively common.
b) Cl (Chlorine): Chlorine is not a rare halogen. It is the second element in the halogen group and is widely used in various industrial and chemical processes.
c) I (Iodine): This is not the correct option. It is the fourth element in the halogen group and is less abundant compared to elements like fluorine and chlorine. Iodine has important applications in medicine and is used in the production of thyroid hormones.
d) At (Astatine): Astatine is the rarest naturally occurring halogen. It is a radioactive element and is generally produced synthetically in laboratories. Due to its radioactivity and scarcity, astatine is not commonly encountered.
