Yes, all noble gases except helium have 18 electrons in their outer energy level, which corresponds to a full valence shell. Helium has only 2 electrons in its outer shell, which is the maximum for its first energy level. The other noble gases, such as neon, argon, krypton, xenon, and radon, have 8 electrons in their outer shell, making them chemically inert and stable. The electron configuration of these elements contributes to their lack of reactivity.
What else can I help you with?
How many valence electrons each noble gas has?
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.
How many valence electrons do all noble gases have except helium?

How many electrons do the noble gases have in there outer energy levels?
8, with the exception of helium which has 2.

How many electrons does noble gases have in the outer shell?
8 electrons (except for helium which has 2)
What contains 8 electrons in the outermost energy level?

How many electrons are present in the valence level for all noble gases except helium?
There are 8 electrons present in the valence level for all noble gases except helium. This is because in the outermost shell, known as the valence shell, noble gases (excluding helium) have a full octet of electrons, making them stable and unreactive.
How many valence electrons do noble gases have?
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
All noble gases have 8 valence electrons except for?
Helium is the noble gas with only 2 valence electrons
How Many valencevelecrtons do the inert noble gases have?
8 valence electrons. except for helium which has 2 valence electrons
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
