What is the number of electrons in neptunium?
The outer shell of neptunium atom has two electrons.Valences of neptunium are between 3 and 7.
Will neptunium float or sink in mercury?
The accepted average density of Neptunium is 19.38 g/cm3 (it is radioactive with several isotopes with somewhat different inherent densities) The average density of Mercury is 13.534 g/cm3 Since Neptunium is more dense than Mercury a sample would be expected to sink in Mercury

What are some chemical properties for neptunium?
- valences of neptunium: 3 to 7- Pauling reactivity: 1,36- as a powder is pyrophoric- can react with the majority of non metals- react with acids- it is easily oxidized
Is neptunium combustible?
Neptunium is a radioactive metal that is not combustible under normal conditions. However, it can react with oxygen in the air to form oxides, which can be potentially flammable. Special precautions are taken when handling neptunium due to its radioactive nature.
Can you mixed Neptunium with elements?
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.
What substances chemically combine with neptunium?
Neptunium can chemically combine with a variety of substances, including oxygen, nitrogen, halogens (such as chlorine), and various other elements. It can form compounds like neptunium dioxide (NpO2), neptunium tetroxide (NpO4), and neptunium nitride (NpN). The specific compounds formed depend on the conditions and elements present during the reaction.
Is neptunium corrosive?
Neptunium is dangerous due to it's radioactivity- it is similar to Uranium or Plutonium. It is likely to be chemically poisonous, but the radiation effects outweigh the chemical hazards. Neptunium is rarely found in a pure state, and results from decay of other radioactive materials, such as Plutonium and Americium.
What is neptunium trifluoride used for?
Neptunium trifluoride is an intermediate for the preparation of neptunium metal.

- Pauling electronegativity: 1,38- valences: 3 to 7- is pyrophoric- has 4 allotropes- reacts with acids- react with nonmetals
Is neptunium a nonmetal?
Neptunium is a metal.
What are the three common compounds of neptunium?
The three common compounds of neptunium are neptunium dioxide (NpO2), neptunium trichloride (NpCl3), and neptunium tetrafluoride (NpF4).
How was neptunium separated into individuals elements?
Neptunium is an individual element; isotopes of neptunium are not separated.
