What are the 2 isotopes of uranium?
It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth’s crust. The decay product uranium-234 is also found. Other isotopes such as uranium-233 have been produced in breeder reactors.
What are the 3 isotopes of uranium?
Uranium is a chemical element with the symbol U and the atomic number 92. There are three naturally occurring isotopes of uranium: uranium-238, the heaviest and most abundant, uranium-235 and uranium-234. Uranium-235 is the only isotope that undergoes fission.
Which of the following isotopes can be obtained while mining uranium?
Uranium Isotopes When uranium is mined, it consists of approximately 99.3\% uranium-238 (U238), 0.7\% uranium-235 (U235), and < 0.01\% uranium-234 (U234). These are the different uranium isotopes.
What are 3 elements we use to produce nuclear energy?
All matter is composed of elements. The important elements for our discussion of nuclear energy are uranium, plutonium, carbon and hydrogen. Uranium and plutonium are involved in nuclear energy production, and carbon and hydrogen are the main elements in conventional fuels like coal, oil and natural gas.
How are uranium isotopes made?
The isotopes 236, 233 and 232 of uranium are formed in reactors from captures of neutrons not followed by fission. Uranium-233 is formed by a similar capture by a nucleus of natural thorium, followed by two radioactive transformations. Uranium 233 is fissile itself.
What is the process of mining uranium?
Mining: When uranium is near the surface, miners dig the rock out of open pits. Open pit mining strips away the topsoil and rock that lie above the uranium ore. When uranium is found deep underground, miners must dig underground mines to reach it. The rock is then removed through underground tunnels.
Which isotope of uranium will split its nucleus?
uranium-235
nuclear weapons …an atom of the isotopes uranium-235 or plutonium-239, it causes that nucleus to split into two fragments, each of which is a nucleus with about half the protons and neutrons of the original nucleus.
What are 3 pros and 3 cons of nuclear energy?
Pros and cons of nuclear power
| Pros of nuclear energy | Cons of nuclear energy |
|---|---|
| Carbon-free electricity | Uranium is technically non-renewable |
| Small land footprint | Very high upfront costs |
| High power output | Nuclear waste |
| Reliable energy source | Malfunctions can be catastrophic |
