What is a the base of neptunium?

Answer 1

- intermediate in the preparation of plutonium 238 - in the instruments for the detection of high energy neutrons - possible use in the future as material for nuclear weapons - possible use in the future as nuclear fuel

Answer 2

It is the intermediate product between Uranium-238 and Plutonium-239.

Uranium-239 decays to Neptunium-239 with a halflife of 23.5 minutes.

Neptunium-239 decays to Plutonium-239 with a halflife of 2.33 days.

Answer 3

etc.

Answer 4

- intermediate in the preparation of plutonium 238 - in the instruments for the detection of high energy neutrons - possible use in the future as material for nuclear weapons - possible use in the future as nuclear fuel

Answer 5

The base of neptunium is generally considered to be the element bismuth. Neptunium belongs to the actinide series of the Periodic Table, and it usually forms compounds with bismuth as the counterion due to their similar chemical properties.

Answer 6

Neptunium is a chemical element, artificial, actinoid, transuranic, solid, metal, radioactive, able to support a nuclear fission and a nuclear chain reaction, with the atomic number 93, etc.

Answer 7

Plutonium and neptunium are obtained in nuclear reactors:

U-238(n,gamma).................U-239(beta)...................Np-239(beta).................Pu-239

Answer 8

Please explain "base of a neptunium".
If you think to chemistry:
Known hydroxides are Np(OH)3, Np(OH)6, and in special conditions Np(OH)4, Np(OH)5.
