# Is it possible neutron stars are actual elements?

As you go up the periodic table (more protons), the ratio of neutrons to protons steadily increases as well. Are we sure there are absolutely no protons and electrons in a neutron star, or could there be so much more neutrons that we cannot measure any protons and electrons? Perhaps then a neutron star is a nucleus of some huge element with a neutron:proton ratio higher than we can distinguish.

from what is written in wiki I guess the short answer is no, as a neutron star contains ions, electrons and nuclei you could probably not call the whole thing an element: upload.wikimedia.org/wikipedia/commons/thumb/9/9e/… –  DrCopyPaste Apr 7 at 11:32
You should provide some reference to what is considered an element. –  harogaston May 3 at 3:12

Neutron stars are not to be considered as an homogeneous object, they have different properties at different layers which are dependant on pressure and temperature for example. Thus in the core below some critical temperature you could have superconductant protons (or any charged baryon) thus meaning you would not find atoms, but more like a soup of free particles. In conclusion I don't see how could this fall into the definition of a chemical element.

A neutron star is made of collapsed matter. The electrons of the atom have been pushed into the nucleus and probably the nucleus of all the atoms have combined into one mass. Therefore, it is likely that you have N neutrons and 0 protons.

according to wiki, this is wrong: upload.wikimedia.org/wikipedia/commons/thumb/9/9e/… –  DrCopyPaste Apr 7 at 11:30
I was thinking about the inner core where the pressure will collapse the atoms. The outer layer would be similar to the sun's outer layer. The wiki has an inner layer that didn't occur to me. –  LDC3 Apr 7 at 13:19
