Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. halogens.
The elements in Group 17 of the periodic table are known as halogens. This group includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Halogens are highly reactive non-metals, characterized by having seven electrons in their outermost shell, which makes them eager to gain one electron to achieve a stable electronic configuration. They commonly form salts when combined with metals and are widely used in disinfectants, pharmaceuticals, and industrial chemicals. Their reactivity decreases down the group.
