Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
Argon and Helium are part of the noble gasses family.
Helium is an inert gas. It has 2 electons.it is non reactive.
Helium is a member of the family of noble gases.
No, helium argon and radon are members of the noble gas family.
Hydrogen and helium aren't 'out' of the periodic table, hydrogen just has characteristics that match up with group one (very reactive) and helium has characteristics that match up with group 8 (non reactive).
