What are valence electrons and how do they relate to the noble gases?

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.

How many electrons are in the outermost energy level of noble gases?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
All noble gases except helium have this?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
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.
Why are noble gases put in the same group?
Because all noble gases have completely filled valence orbitals. Helium has 2 valence electrons whereas all other noble gases have 8 valence electrons.
What is the outer shell of the noble gases called?
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.
Which group contains eight valence electrons?
Group 18 contains eight valence electrons, namely the noble gases.
