Periodic Table Group 17: The Halogens

The question asks to identify which elements are located in the 17th group of the periodic table.

Understanding the Periodic Table Groups

The periodic table organizes chemical elements into rows called periods and columns called groups. Elements within the same group typically share similar chemical properties because they have the same number of electrons in their outermost electron shell (valence electrons).

Group 17 Elements: Halogens

• The 17th group of the periodic table is home to the Halogens.
• This group includes the elements: Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), Astatine (At), and Tennessine (Ts).
• Halogens are highly reactive nonmetals. They tend to gain one electron to achieve a stable electron configuration, forming salts with metals (hence the name "halogen," meaning "salt-former").

Analyzing Other Options

• Noble Gases: These elements are found in Group 18. They are known for their lack of reactivity due to having a full outer electron shell.
• Chalcogens: This is the name given to the elements in Group 16 (Oxygen, Sulfur, Selenium, etc.). They typically form compounds with a -2 oxidation state.
• Boron: Boron (B) is the first element in Group 13 of the periodic table. It is a metalloid.

Therefore, the elements located on the 17th group on the periodic table are the Halogens.
