Example: the Li atom. In the design below you see how the Li atom is the result of joints between proton micro-tubes (and underlying micro-tubes), neutron-tubes, electron, etc. As explained in another part of this website the angle to make a pelastration possible can be determinant. For this reason we see in nature that bindings are only possible in specific angles.

Now there is some extra in relation to the chemical and nuclear fields. It makes sense to state that the pelastration factor between certain micro-tubes is very strict, and that the accumulated gravitational fields + internal levels may only pass the [P] port till a certain point, for example provoked by a prior-port (compare it with a knot in a sailing rope). That way the pelastrating tube is blocked from the back. This means that that tube will have a specific limited length for all tubes of that quality when pelastrating a specific type of micro-tube. This limited length might be interesting when oppositional micro-tube can't reach each other but create between their heads resonance fluxes which can new behavior in third micro-tubes (e.g. create spin)

This applies to particles, electrons, and all chemical reactions.

		An impacting (incident) tube may also pass through a tube which contains several inserted tubes, fixing them all to a specific position.
