Step 1
Name the group in the periodic table
Answer
The group in the periodic table whose elements are chemically unreactive due to their stable electron configurations is known as the noble gases. This group is also referred to as Group 18 in the periodic table, or alternatively, it can be called Group 0. The elements in this group include helium, neon, argon, krypton, xenon, and radon, all of which have full valence electron shells, making them stable and unreactive.
