Answer:

Group VIII or the inert gases, or noble gases.

Explanation:

All of the elements of this family of elements are mainly inert and undergo few or no chemical reactions.

All of the elements of this group except Helium have 8 valance electron which results in a stable filled electron shell. Helium has only 2 valence electrons but these two electrons fill the first shell providing Helium with an analogous stable structure to the other VIII A elements.
