Noble gases belong to which of the following groups of the periodic table?

18

The correct answer is option 2. 18.

Noble gases belong to Group 18.

Noble gases are also known as Group 18 elements or the "noble gases" group. They are located on the far right of the periodic table and include elements such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements have full valence electron shells, making them highly stable and non-reactive under normal conditions.
