To perform direct enrichment assay on gaseous uranium hexafluoride (UF6) with laser induced breakdown spectroscopy (LIBS), the dominant spectral-line features, evolution of the signal and background of the U II 424.437 nm line, and its Stark width and shift, were studied as a function of UF6 gas pressure and pulse energy of a nanosecond Nd:YAG laser. Complete table of nuclides. Uranium-234 ( 234 U, U-234) is an isotope of uranium. In natural uranium and in uranium ore, 234 U occurs as an indirect decay product of uranium-238, but it makes up only 0.0055% (55 parts per million) of the raw uranium because its half-life of just 245,500 years is only about 1/18,000 as long as that of 238 U. How many electrons in 234U? - Answers. Uranium's atomic number is 92, which is the number of protons inthe nucleus of a uranium atom. A neutral uranium atom has 92electrons, the same as the number Uranium-234.
