Hello Everyone,
Something has been itching at me and I want to ask this.  I am very much a layman when it comes to this subject.   But is there Is there a way of reducing the distance of the electrons to the molecular core?  Is there a way of increasing the pull of the central charge to reduce the radius of the electron's spatial expanse?  Any way of utilizing say an electric field to strengthen the molecular pull and see what happens when you reduce the size of where the electrons move?  Would this reduce the size of objects like when a star becomes a neutron star.  A teaspoon of such material is hundreds of thousands of tons.  Could we, with a field, somehow, condense the space?  Reduce the molecular empty space and so make it smaller?   We can split atoms but can we compress them and what ramifications would this have on what was reduced?

Decreasing the radius of an atom would indeed have important implications. When you replace electrons with muons, the radius of the atom decreases about 200-fold due to the muon's much greater mass. This allows the muonic atoms to approach each other much more closely, making processes like nuclear fusion far easier to initiate. This muon-catalyzed fusion can even take place at room-temperature, making it a genuine form of "cold fusion". Unfortunately, muons are exceedingly unstable, so efforts to utilize this for energy production have been frustrated.

I'm not sure how you'd do that with normal atoms without resorting to regular old compression. If there was some way to use magnetic fields to do it, the field would likely need to be immensely powerful and require enormous power input.

Yes, you can see the effects of increases positive charge on the nucleus by looking at successively heavier elements.

The inner electrons of an atom are in the 1s shell.
- As the positive nuclear charge increases, the average radius of this shell decreases, and the energy of electrons dropping into this shell increases, due to the inverse square law of electromagnetism.
- For low-mass elements like hydrogen and helium, electrons dropping into the 1s shell can produce light in the visible and ultraviolet range.
- For high-mass elements, electrons dropping into the 1s shell will produce X-Rays, which are much more energetic than visible light.
 - That is why X-Ray machines use targets made of elements like Rhenium (element 75) and Tungsten (element 74).
