P-239 and P-241
Plutonium has no natural isotopes. All plutonium isotopes are artificially produced through nuclear reactions.
The isotopes are uranium-235 or plutonium-239.
The nuclei of different plutonium isotopes all contain 94 protons, which define the element as plutonium. The isotopes differ in the number of neutrons they contain, resulting in different atomic masses for each isotope.
The mass number of plutonium isotopes can vary depending on the specific isotope. Common plutonium isotopes include plutonium-238, plutonium-239, and plutonium-240, with mass numbers of 238, 239, and 240 respectively.
All the uranium isotopes are radioactive.
On long term, the useful isotopes of plutonium are not renewable.
no. it is a solid isotope and is the least harmful of the plutonium isotopes.
yes
All the isotopes of uranium and plutonium are radioactive; plutonium isotopes have a greater specific activity. For cerium: the isotopes 136Ce and 142Ce are possible to be radioactive but having very long half lives and a not significative radioactivity.
Natural isotopes of plutonium exist only in traces in uranium ores.
The isotopes 239Pu and 241Pu are easily fissionable; also the isotopes of plutonium has a small criticall mass and the energy released by fission is enormous.
Plutonium is an artificial element; traces (extremely low) of plutonium isotopes of natural origin exist in uranium ores. Plutonium is used in nuclear weapons and nuclear fuels.
