What is Np? Important knowledge about Np.

  1. Definition of Np
    Neptunium (Np) is a chemical element with the symbol Np and atomic number 93 in the periodic table. It is the first man-made chemical element, hence it does not naturally occur on Earth.
    1.1 Names
    1.1.1 Common name: Neptunium
    1.1.2 English name: Neptunium
    1.2. Atomic number: 93
    1.3. Atomic mass: 237
    1.4 Ion configuration: Np3+, Np4+, NpO2+

  2. Properties of Np
    2.1 Physical properties of Np
    State of matter: Solid
    Color: Black silver
    Smell: Odorless
    PH level: Not applicable
    2.2 Chemical properties of Np: As a transition metal, it has the ability to form a variety of different compounds.

  3. Common chemical equations involving Np
    Since Neptunium is a man-made element, chemical reactions involving Neptunium are not commonly encountered in daily life.

  4. Preparation of Np
    4.1 Laboratory synthesis of Np:
    Np is synthesized by bombarding Uranium atoms with neutrons, producing the element U-238, which then transmutes into Np-239 through a series of nuclear reactions.
    4.2 Industrial synthesis of Np:
    In industry, Np is usually produced by separating it from nuclear waste after the nuclear fission process.
