I doubt that 2 is a magic number, because I know for certain that Helium has a far lower nucleus energy state than Deuterium. (Source: My Physics school book)
- Interesting. My source is http://www.research.att.com/projects/OEIS?Anum=A018226. I'll check my physics textbooks to confirm, too. Giftlite 23:54, 24 Mar 2004 (UTC)~
I believe the magic numbers refer to number of protons OR number of neutrons, not the sum. So Helium 4 is especially stable because it has both 2 protons and 2 neutrons.

"If the count of protons is one of those magic numbers, then a neutral atom has the same number of electrons , arranged into complete shells around the atomic nucleus."
Regardless of the magic in the nucleus , ANY neutral atom has the same number of electrons (as protons); and they are NOT necessary complete ELECTRONIC shells(ie noble gases). I have excized the previous DOUBLELY STUPID sentence. The electron, absent or not, have NOTHING to do with the stability of the nucleus (to any measurable extent).67.124.102.77 06:05, 4 Jan 2005 (UTC)
Furthermore, the magic numbers for electrons are different than those of protons and nuetrons. That statement leads to the idea that a magically numbered atom is particularly stable electronically also, which is not the case.
