How many electrons are present in the valence level for all noble gases except helium?
There are eight in all noble gases (except helium) because that forms a "full level" so that they are noble gases and not reactive.
How many valence electrons do all noble gases have except helium?
All noble gases have 8 valence electrons. Helium has only 2.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
All noble gases have 8 valence electrons except for?
Helium is the noble gas with only 2 valence electrons
Why does helium belongs to group 8 while it has 2 electrons in its outer shell?
Helium belongs to group 18 elements along with other noble gases. All noble gases except helium have completely filled s and p orbitals. Helium has completely filled 1s orbitals and hence is kept along with the noble gases.

Are helium and xenon and neon noble gases?
Yes, they are all noble gases.

Do all noble gases have eight valence electrons?
Yes, except for helium which only two electrons. All noble gases are found under the noble gas family to the far right of the periodic table.
How many electrons are found in the outer lever of all the noble gases except helium?
2 electrons are found in the outermost electron shell of Helium. 8 electrons are found in the outermost electron shell of all other noble/inert gases.
What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
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 does helium differ from the other elements in its family noble gases?
It differs because it only has 2 electrons in its valence shell, and all the other noble gases have 8 electrons.
Helium neon argon or krypton what are they called?
They are the Noble(Inert) gases.
