From the UVS perspective, the electron pairs of the s-subshells, are the cyclonic bipolar polar vortex pairs of accreting spinor fields manifested on the hypersphere of a nested electron shell.
The outer s-subshell of an atom, is always an exposed subshell, and it thus is always a valence shell.
Animation on right illustrates how a torus could be transformed, it shows as the distance to the axis of revolution decreases, the ring torus becomes a horn torus, then a spindle torus, and when the distance approaches zero, the torus will resemble a sphere.
The postulated nested dual-core 3-sphere hypersphere for the idealised nested electron shell as illustrated below, can be perceived in its frame of reference to be extrinsically spinning in counterclockwise direction for the nested 1st cyclonic sphere.
The UVS atomic model shows that the subshells of 2s, 3s, 4s, and so forth, perceivably are the inner walls of the torus-shaped nested electron shells, and thus they are nearer to the nucleus than the 1s subshell, with the 4s subshell being the nearest to the nucleus among these subshells; the nested s-subshells are vortically formed in the vortex column around its atomic nucleus.And electron has mass, it therefore can interact to manifest its secondary Lagrangian points.electrons can be perceived as negative charge fields that are vortically manifested by the nested dual-core spheroidal unisonal vortex, which encapsulates its atomic nucleus in an atom.The first nested cyclonic spheroidal unisonal vortex (1st sphere as illustrated above in the image of the UVS atomic model) is centered from the nucleus, the second nested cyclonic spheroidal unisonal vortex (2nd sphere) is centered from the L1 Lagrangian point, and the third nested anti-cyclonic spheroidal unisonal vortex (3rd sphere) is centered from the L2 Lagrangian point; this is the postulated structure of the nested 3-sphere hypersphere electron shell.Heuristically, the second spheroidal unisonal vortex and the third spheroidal unisonal vortex, are vortically merged externally to form as an oval-shaped vortical structure within the first spheroidal unisonal vortex.Note: The postulated arrangement of the s-subshells based on the UVS atomic model with its hypothetical nested torus-shaped structure, paradoxically differs with the standard atomic model.
