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 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.


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.


All noble gases have 8 valence electrons except for?

Helium is the noble gas with only 2 valence electrons


How many electrons are found in the outer lever of all the noble gases except helium?

There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.


Are helium and xenon and neon noble gases?

Yes, they are all noble gases.


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.


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.


Helium neon argon or krypton what are they called?

They're all Noble gases.


Which non-metals are noble gases?

The noble gases are helium, neon, argon, krypton, xenon and radon.


What are all the elements of noble gases?

All of the group 8 (group 0) elements - Helium, Neon, Argon, Krypton, Xenon, Radon
