And that is the formula
I learned To From My Chemistry Teacher Mr Whetstone! OHHH YEAHH CHEEE
Helium has only two electrons in the valence shell (or the only shell it has). All other noble gases have eight electrons in their valence shell (or the outer most shell).
Helium has 2 electrons in its outer most orbit. Other noble gases have eight valence electrons.
They all end (have valence electrons) in s2 p6. Only the principle quantum number (n; shell) is different.
There is none because there is no noble gas above Helium
noble gases Helium has 2 valence electrons, whereas the rest have 8.
There is no boble gas notation for hydrogen and helium. The noble gas notation starts for elements after helium. The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point forward.
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration.
helium, neon, argon, krypton, xenon, and radon.
Helium's electron configuration is 1s2. Neon's electron configuration is 1s22s22p6. All of the rest of the noble gases, like neon, have the maximum number of electrons in their outermost s and p orbitals (valence shells), which is eight.

The electron configuration of helium is: [Xe] 4f15d16s2.
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
By acquiring noble gas configuration elements become stable .
Because helium has completely filled valence orbitals similar to other noble gases.
helium, neon, argon, krypton, xenon, and radon.
