Helium is a noble gas because
WebLet's start with the prior that in a hydrogen atom the principle quantum number determines the energy - so maybe full shells correspond to noble gases. Now, I understand that in helium the n=1 level is full, so it is a noble gas. Then, beryllium has a full 2s subshell, but empty 2p, so it is a metal. Neon has the n=2 level full, and is a noble gas.
