14Np
14Np is not a standard designation in established scientific nomenclature. The symbol Np denotes the element neptunium, a radioactive actinide, and in nuclear science isotopes are typically written with a mass number either as a superscript or as a dash, for example Np-237 or Np-239. There is no known or stable neptunium isotope with mass number 14, so the form 14Np does not correspond to a recognized nuclide designation. In practice, if a document uses 14Np, it is likely a misprint or a nonstandard shorthand rather than a formal scientific term.
In non-scientific contexts, 14Np may appear as a catalog code, model number, batch identifier, or internal label
