Uranium 235 has 92 protons and electrons, 143 neutrons, atomic mass is cca. 235, is a natural isotope. Plutonium 239 has 94 protons and electrons, 145 neutrons, Atomic Mass is cca. 239, is an artificial isotope. Plutonium is more toxic than uranium. Also are differences in the types of radiations emmited, half-life and many other chemical and physical properties.

What is the most fissionable material?
Plutonium-239 and Uranium-235
Name two possible fuel sources for a nuclear reactor?
Uranium (enriched in U-235), plutonium
What element is a reactor fuel?
Uranium-235 or Plutonium-239, or Uranium-233. Also many transuranics, like Americium make good fuel.
What is the use radioactive isotope in energy generation?
The most useful isotope is uranium 235 which occurs naturally as 0.7 percent uranium as found. Plutonium 239 is also useful but has to be made in a reactor from uranium 238
What are the similarities and differences between the isotopes uranium 235 and uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. And of course the atomic masses are different.
Similarties between uranium-235 and plutonium-239 in nuclear reactors?
Uranium 235 and Plutonium 239 are fissile elements, fissionable with thermal neutrons.
What 2 radioactive elements were chosen for the atomic bomb?
Uranium and Plutonium
To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
What is the most fissionable material?
Plutonium-239 and Uranium-235
What element uses breeder reactor uranium or plutonium?
Uranium and plutonium are both actinides that are used in nuclear reactors.
Which uranium isotope is the first step in the chain of events making plutonium-239?
Uranium 235
Which material type is more dangerous plutonium 239 or uranium 235?
Plutonium is more toxic and radioactive.
What kind of rays does uranium 235 and plutonium 239 release?
Plutonium 239 emit: alpha, gamma, spontaneous fission neutrons Uranium 235 emit: alpha, gamma, spontaneous fission neutrons
What else other than uranium 239 is the atomic bomb made of?
Not uranium 239, but uranium 235 and plutonium 239.
A radioactive element often used in nuclear power stations?
Uranium 235 or Plutonium 239
Is uranium or plutonium used as fuel in a nuclear reactor?
Though both enriched uranium and plutonium can be used, the most common in enriched Uranium-235. The waste that comes from the reaction is a mix of elements (uranium, plutonium, etc) http://en.wikipedia.org/wiki/Nuclear_power
What element was used to make the atom bomb?
Plutonium-239 for Nagasaki's Fat Man Uranium-235 for Hiroshima's Little Boyhydrogen
