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). WebJan 30, 2024 · However, the electron can exist in spin up (m s = +1/2) or with spin down (m s = -1/2) configurations. This means that the s orbital can contain up to two electrons, the p orbital can contain up to six electrons, the d orbital can contain up to 10 electrons, and the f orbital can contain up to 14 electrons.
