There aren't any gaps in the periodic table, but in theory you could have more and more elements at the top end, in extreme conditions and perhaps for very short times.And a neutron star, by definition, doesn't have any protons as they have all been converted to neutrons, so can't be considered an atomic nucleus. The atomic number is the number of protons in the nucleus.
Proceeding inward, one encounters nuclei with ever increasing numbers of neutrons; such nuclei would decay quickly on Earth, but are kept stable by tremendous pressures.Proceeding deeper, one comes to a point called neutron drip where neutrons leak out of nuclei and become free neutrons. In this region, there are nuclei, free electrons, and free neutrons. The nuclei become smaller and smaller until the core is reached, by definition the point where they disappear altogether.
I have (for once ) a sensible question, when was the Periodic Table first compiled, and have we filled all the gaps yet, or are there more elements to be discovered ?

However, I assume that the farther you go on this infintely big periodic table, the more incredibly unstable the elements would be-maybe even being detectable for far less than milliseconds. Also, assuming that the next element in Group 1 had the same characteristics as all the other elements except for hydrogen, it would be incredibly explosive in water (look up francium in water videos on youtube).
