All noble gasses have 8 valence electrons, it is what makes them "stable" and therefore are non reactive.
helium (He) because it only has 2 electrons
Helium has only 2 valence electrons.
Helium, He, which has only two, 1s2
Helium
Helium
a filled highest occupied principal energy level
Elements in group 8A of the periodic table, known as the noble gases, do not readily form chemical bonds because they have a fully occupied valence shell of electrons. This stable electron configuration makes them highly unreactive, as they do not have a tendency to gain, lose, or share electrons with other elements. Consequently, noble gases exist as monoatomic gases and are generally chemically inert.
Noble gases
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
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.
The valence electron shell of noble gases is full.
they are all completely filled in the case of noble gases
Because it has it has eight electrons in the outermost occupied energy level.
a filled highest occupied principal energy level
All of the Nobel gases do (He Ne Ar Kr Xe and Rn)

Noble gases
Another word for a noble gas is an inert gas. These elements have the maximum electrons in their highest energy level.
it has eight electrons in its outermost shell, which is one of the qualifications of the first three noble gases. The highest energy level refers to the atoms outer shell of electrons
Neutral gases do not; ionized gases do.
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
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.
