Question

What is the name for the group of elements that are particularly unreactive?

Answer 1

`"The Group 18 elements"`

Explanation:

The helium, neon, argon group were once known as the `"Noble Gases"` as they were thought to be inert, and hence did not undergo reaction with the other (common) elements. These days, a few Noble gas compounds are known, but notably with fluorine and oxygen, which are the most reactive elements on the Periodic Table.
