Helium number of valence electrons

WebThe duet rule or duplet rule of the first shell applies to H, He and Li—the noble gas helium has two electrons in its outer shell, which is very stable. (Since there is no 1 p subshell, 1 s is followed immediately by 2 s, and thus shell 1 can only have at most 2 valence electrons). WebTo write the orbital diagram of lithium, you have to write the orbital notation of lithium. Which has been discussed in detail above. Lithium (Li) orbital diagram. 1s is the closest and lowest energy orbital to the nucleus. Therefore, the electrons will first enter the 1s orbital.
