Question

why group 18 elements are called inert gases? write the electronic configuration of group 18 elements
​

Answer 1

Explanation:

The noble gases are in Group 18. They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. ... Because this configuration is extremely stable as well as symmetrical, the noble gases are very unreactive.

Hope it helps :))
