Review for Chapter 7
... 28. The energy of the electron in a hydrogen atom is determined solely by its principal quantum number, n. 29. No two electrons in an atom can have the same four quantum numbers (Pauli exclusion principle). 30. The most stable arrangement of electrons in a subshell is the one that has the greatest n ...

Spin in Physical Space, Internal Space, and Hilbert
... This field theory description does not yet quite correspond to the picture of polyacetylene sketched in the previous section, because the breaking of translational symmetry (from x → x + a to x → x + 2a) has not appeared. We need not change the equations, however, we need only draw out their implica ...
