It is possible. Neptunium can decay by spontaneous fission, and ytterbium is a possible daughter, although vanadium would have to be the co-daughter. (93NP --> 70Yb + 23V) It seems unlikely, however, as the split would more likely be closer to centerline mass.
Promethium is not in the neptunium series of radioactive decay.
When neptunium disintegrates, it typically forms elements such as plutonium, americium, and curium through a process called radioactive decay. These elements are sequentially produced as neptunium undergoes nuclear reactions, leading to the creation of heavier elements.
After an alpha decay the atomic number of the new element formed is less with 4.
Neptunium is a solid metal.
Neptunium itself is an element, the simplest form of matter.
Yes, neptunium can be mixed with other elements to form compounds and alloys. Neptunium is a radioactive element, and its compounds are primarily produced for research purposes. Various elements such as oxygen, fluorine, and hydrogen can combine with neptunium to form different compounds.
Neptunium is a metal, and therefore it can in theory form all the usual kinds of compounds that metals form; it could combine with oxygen and form neptunium oxide. However, neptunium is a radioactive element with a very short half-life, therefore it does not stick around long enough to engage in chemical reactions, or even if it did, the resulting compound would also exist only for a very brief period of time.
Any element; neptunium can form himself a critical mass.
Ytterbium itself is not considered dangerous to humans in its elemental form. However, ytterbium compounds can be toxic if ingested or inhaled, so proper handling and safety precautions are necessary when working with these materials.
Ytterbium is not considered flammable. It is a rare earth metal that is stable in air and does not burn easily. However, like many metals, when finely divided or in powder form, it can pose a fire hazard and react with moisture or acids. In its bulk form, ytterbium does not ignite or support combustion.
Ytterbium chloride is an ionic compound, meaning it has an ionic bond. This is because ytterbium is a metal and chlorine is a non-metal, causing them to form an ionic bond due to the transfer of electrons.
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.
