No, a nucleus cannot be made with two or more neutrons and only one proton. The number of protons in an atomic nucleus determines the element to which it belongs. The element with one proton is hydrogen. If you have two or more neutrons and only one proton, it wouldn't correspond to a stable or naturally occurring element.
The stability of atomic nuclei depends on the balance between the number of protons and neutrons. In general, larger atomic nuclei tend to have a greater number of neutrons compared to protons to maintain stability. However, for smaller nuclei, the number of protons and neutrons is usually approximately equal.
It's worth noting that there are isotopes of elements that have more neutrons than protons. These isotopes are characterized by having different mass numbers but the same atomic number. However, in these cases, the number of protons is always greater than or equal to one.
