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.
All noble gases have 8 valence electrons. Helium has only 2.
Helium has only 2 valence electrons. The rest noble gases have eight.
Yes, all noble gases have eight valence electrons, except for helium which has only two valence electrons. This stable electron configuration is known as the octet rule.
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.

Helium is the noble gas with only 2 valence electrons
Yes, they are all noble gases.
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.
Each noble gas has 8 valence electrons, except for helium which has 2 valence electrons. This full outer electron shell gives noble gases their stability and lack of reactivity.
They are called noble gases.
The noble gases are helium, neon, argon, krypton, xenon and radon.
Helium differs from other noble gases in its smaller atomic size and lower atomic mass. It is also the only noble gas that does not have a full shell of electrons, containing just 2 electrons in its outer shell. Additionally, helium is the least reactive of the noble gases due to its stable electron configuration.
