In which group are the non-metal elements placed in a vertical column on the right side of the periodic table?

Correct option is C

In the periodic table, the non-metal elements placed in a vertical column on the right side are called the "group 17" elements, also known as the halogens.
• This group includes elements like fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). However, it's important to note that not all non-metal elements are in group 17.
• There are other non-metals scattered throughout the periodic table, primarily on the right side, such as nitrogen, oxygen, and the noble gases in group 18 (helium, neon, argon, etc.).
