Plutonium is more dangerous: the specific activity is greater, the critical mass is smaller, the chemical toxicity is greater.
Yes, plutonium is generally considered to be more powerful than uranium because it is a more efficient fuel for nuclear reactors and can sustain nuclear chain reactions more easily. Additionally, certain isotopes of plutonium are used in nuclear weapons due to their high explosive potential.
Plutonium has the same composition as uranium, except for the fact that it contains one more neutron and one more proton. Actually Plutonium-239 has 2 more protons and 2 more neutrons than Uranium-235.
The Pauling electronegativity of uranium is 1,38; the Pauling electronegativity of plutonium is 1,28.So, plutonium is a bit more chemically reactive than uranium.
The critical mass of plutonium is lower, plutonium is not so expensive as highly enriched uranium, the technology to obtain plutonium is more simple than the isotopic separa-tion of uranium, etc.
Plutonium and uranium can form alloys.
Uranium and plutonium can form alloys.
Hydrogen bomb gets some of its energy from fusion, uranium or plutonium bomb gets all of it from fission. Either can be more powerful, depending on the design. The most powerful bombs built have all been hydrogen bombs.
No, plutonium is used more. Uranium can only be used in gun type nuclear weapons, which are rarely used.
Yes, it is possible to recycle "burned" uranium and plutonium.
The atomic radii of uranium and plutonium are identical.
Plutonium is obtained from uranium irradiated in nuclear reactors, consequently the production of plutonium depends on uranium resources.
Uranium is not easily obtained; and the technology of plutonium is extremely difficult.
