Exemplar Problems

Problem 1 : which group of the periodic table contains the most reactive nonmetals, and why?

Solution :

The group of the periodic table that contains the most reactive nonmetals is Group 17, also known as the Halogens group. This group includes elements like fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). Halogens are highly reactive nonmetals because they have a strong tendency to gain one electron to achieve a stable noble gas electron configuration.
