[5][6] Sommerfeld retained Bohr's planetary model, but added mildly elliptical orbits (characterized by additional quantum numbers and m) to explain the fine spectroscopic structure of some elements. So for lithium, the third electron rests in the second shell. The third shell can hold 32 electrons. During this period Bohr was working with Walther Kossel, whose papers in 1914 and in 1916 called the orbits "shells". "Niels Bohrs Second Atomic Theory". What's the difference between an electron shell and subshell? For example, looking at the top two rows, every shell has an s subshell, while only the second shell and higher have a p subshell (i.e., there is no "1p" subshell). The 2p,3p, 4p, and 5p can each hold six electrons because they have three orbitals. For the third shell, $n=3$, so the allowed values of $\ell$ are: $\ell=0$, which is the $s$ subshell, $\ell=1$, which is the $p$ subshell, and $\ell=2$, which is the $d$ subshell.
