  Following a previous proposition of quaternity spacetime for electronic
orbitals in neon shell, this paper describes the geometrical course each
electron takes as it oscillates harmonically within a certain quaternity space
dimension and provides the concrete connections between geometries and
trigonometric wavefunctions that observe Pythagorean theorem. By integrating
four quaternity space dimensions with conventional Cartesian coordinate systems
in calculus, we explain electronic motions by the Maxwell equation and general
Stokes theorem from the principles of rotation operation and space and time
symmetry. Altogether with the previous reports, we have effectively established
quaternity spacetime as a successful theory in elucidating the orbital shapes
and motions of electrons within inert atoms such as helium and neon. We point
out once again that 2px, 2py, and 2pz orbitals have different geometrical
shapes as well as orthogonal orientations, contrary to the traditional 2p
orbital model.
