8, with the exception of helium which has 2.
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
No, you are misinformed, it is electrons not gasses that fill energy levels.

Noble Gases
No. The noble gases are largely nonreactive because their outermost energy levels are complete, making them stable by themselves.
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
No. Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration.
The valence electron shell of noble gases is full.
They r noble gases which have stable valance shell and grotp no. 18
