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.
The atomic bombs dropped on Hiroshima and Nagasaki in World War II used uranium-235 and plutonium-239 as their primary elements. The bomb dropped on Hiroshima (Little Boy) used uranium-235, while the bomb dropped on Nagasaki (Fat Man) used plutonium-239.
Uranium-235 is the most commonly used fissionable material in nuclear reactors. It readily undergoes fission when bombarded by neutrons, releasing energy in the process.
Two examples of nuclear fuels are uranium-235 and plutonium-239. These are commonly used in nuclear reactors to generate electricity through controlled nuclear fission reactions.
The key elements to making fission bombs are: Uranium and Plutonium. The specific isotopes of interest are: Uranium-233, Uranium-235, and Plutonium-239. But many other elements are needed to make a functional bomb. As a very rough guess, about a quarter of the elements on the periodic table are needed somewhere in the bomb, roughly 23 different elements in total.
Uranium-235 and Plutonium-239 are two possible fuel sources for a nuclear reactor. These isotopes are fissile materials that undergo nuclear fission reactions to generate heat in a controlled manner for producing electricity.
Uranium 235 and Plutonium 239 are fissile elements, fissionable with thermal neutrons.
Uranium-235 and plutonium-239 were the two radioactive elements chosen for the atomic bomb dropped on Hiroshima and Nagasaki.
Yes, plutonium-239 emits alpha particles by decay.
Uranium 235
The main difference between uranium-235 and uranium-238 is their atomic masses. Uranium-235 has 235 atomic mass units (AMU) while uranium-238 has 238 AMU. This difference in mass is due to the number of neutrons in the nucleus of each isotope.
Not uranium 239, but uranium 235 and plutonium 239.
Plutonium-239 for Nagasaki's Fat Man Uranium-235 for Hiroshima's Little Boyhydrogen
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
We usually find that uranium is used as fuel in nuclear reactors (though some use plutonium).
Uranium 235 Plutonium
Mostly uranium-235, also plutonium
Plutonium and enriched uranium are different materials.Enriched uranium is uranium with a concentration of the isotope 235U greater than the natural concentration of 0,7 %.
