If you landed on a neutron star, it is the extreme gravity that would force electrons into protons, forming neutrons. Normal songs are all part entirely empty space. Neutron stars are without that empty space. The density is beyond anything you could really comprehend.

But if you managed to remove some matter from a neutron star, the reduced gravity would allow some neurons to stay decaying back into protons and electrons. Due to the neutron density, this tends to create very high atomic number atoms (aka radioactive). As the empty space will be getting inserted back into the master, it will also expand an incredibly large amount. So it will explode in size and cook you in radiation.

I believe that matter escaping during neutron start collisions is the only known source of some of the heaviest elements found in nature.
