Noble gases are also known as the inert gases, meaning they don't react because they have a stable octet (eight electrons in their valence shell). They all have eight electrons in their valence shell with the exception of helium because helium is rebel, but they are all nonreactive including helium.
What else can I help you with?
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.
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.
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.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
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.
Why are noble gases put in the same group?

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 valence electrons do noble gases have?
8, 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.
Which group contains eight valence electrons?
Group 18 contains eight valence electrons, namely the noble gases.
Which families contains a full octet of valence electrons?
These are the noble gases.
How many valence electrons do all noble gases have except helium?
All noble gases have 8 valence electrons. Helium has only 2.
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 Valence electrons are in noble Gases?
eight
