Halogens have 7 valence electrons and nobel gases have 8. Each atom wants 8 or none electrons according to the octet rule. Therefore, nobel gases are relatively unreactive b/c they already have 8 Halogens only need 1 more valence electron, making them very reactive.
They have a full octet of electrons.

Helium IS a Nobel gas and heads that group. It may not have the full 8 electron octet, but it is just as naturally non-reactive as the other Nobel gases.

A full octet, valance shell. A valance shell with eight electrons, such as the Nobel gases have, doe not need to donate or accept electrons into or out of the valance shell to be stable.
In simple terms they all have the stable octet.
The full octet means the element is inert (non-reactive.)
Noble gases have completely filled octet. It makes it difficult to get unstable.
They have a full octet of electrons.
