Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Group 18.
- The noble gases (Group 18) are located in the far right of the periodic table.
- They were previously referred to as the "inert gases" due to the fact that their filled valence shells (octets) make them extremely nonreactive.
- The noble gases were characterized relatively late compared to other element groups.
