What is the atomic number of uranium-235?

Uranium-235 (235U) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a fission chain reaction….Uranium-235.

What is the atomic number of uranium?

92
Uranium/Atomic number
Uranium is a silver-gray metallic chemical element in the actinide series of the periodic table that has the symbol U and atomic number 92.

What is the electron of uranium-235?

92 electrons
A neutrally charged atom of uranium-235 will have 92 electrons orbiting its nucleus.

Where can I find information about uranium 235?

Please visit the Uranium element page for information specific to the chemical element of the periodic table. More… The data from CAS Common Chemistry is provided under a CC-BY-NC 4.0 license, unless otherwise stated.

What happens at low concentrations of uranium 235?

A critical chain reaction can be achieved at low concentrations of U-235 if the neutrons from fission are moderated to lower their speed, since the probability for fission with slow neutrons is greater. A fission chain reaction produces intermediate mass fragments which are highly radioactive and produce further energy by their radioactive decay.

How much energy does one atom of uranium 235 produce?

The fission of one atom of uranium-235 generates 202.5 MeV = 3.24 × 10−11 J, which translates to 19.54 TJ/mol, or 83.14 TJ/kg. This is around 2.5 million times more than the energy released from burning coal.

How does uranium enrichment lead to depleted uranium?

Depleted uranium. Enrichment processes generate uranium with a higher-than-natural concentration of lower- mass-number uranium isotopes (in particular U-235, which is the uranium isotope supporting the fission chain reaction) with the bulk of the feed ending up as depleted uranium, in some cases with mass fractions of U-235…
